  1. you need to do the mulitplication before subtraction

    so you have

    6(3x-5) = 18x - 30

    so you have

    18x - 30 - 7x = 25

    11x - 30 = 25

    11x = 55

    x = 55/11

    x = 5


  2. first you want to distribute the 6

    you do that by multiplying

    so you get 18x-30-7x=25

    then you want to combine like terms

    then you would get 11x-30=25

    then you want to move -30 to the other side to make your number with the variable on one side and you constant on the other

    you do this by adding cause the 30 is negative

    that would give you 11x=55

    then to isolate x you would divide by 11 by both sides

    that would give you the answer of x=5

    : )

  3. (3x-5)=(1x)

    sorry but that's all i

    know how to do hope it help

    a little oh and its

    Parentheses

    Exponents

    Multiplication

    Divide

    Addition

    Subtraction

  4. 6(3x-5)-7x=25

    18x - 30 - 7x =25

    11x -30 = 25

    11x = 55

    x =55/11

    x =5

  5. 6(3x-5)-7x=25

    18x-30-7x=25

         11x-30=25

             11x=55

                 x=5

  6. 6(3x-5)-7x=25

    1- distribute the 6 to the 3x and -5

       18x-30-7x=25

    then you add the x's

    18x+-7x=11x

    then you complete this

    11x-30=25

    add 30 to both sides

    11x-30=25

         +30  +30

    11x=55

    then divide by 11 each side

    11x=55

    /11   /11

    x=5   is your answer


  7. Distributive property

    Umm

    Lol I think this is a higher grade level than mine

    But if it's Algebra 1 then I think this is how you do it

    You multiply 6 into 3x then 6 into 5.

    Then i'd think i'd be

    18x -30-7x=30

    Then you prob take 18x and 7x and subtract?

    Then i'd be 11x - 30 = 25

    then you'd add the opposite then it'd be

    11x + -30 =25

    11x +  30= 30

    ____________

    11x = 55

    __    ___

    11x     11x

    lol i looked at the other people

    i thought it was

    9x= 55.

    but its 11x=55

    x=5

    YEAH SON!!!

  8. 6(3x-5)-7x=25

    Distributive Property: 18x-30-7x=25

    Combine like factors: 11x-30=25

    Add (the 30 to the 25): 11x=55

    Divide (55 by 11): X=5

    hope that's right, it's been a long summer!

    hope that helped!

  9. Times everything in the parenthesis by 6.

    6 x 3x = 18x

    6 x -5 = -30

    That leaves you (18x-30)-7x=25

    Get rid of the parenthesis.

    18x-30-7x=25

    Do the math for like terms.   18x-7x= 11x

    So 11x-30=25

    Add 30 to the side with 25 so that you have a variable on one side and a number on the other.  You always take the opposite of the number.  For example, 5 would b -5.

    11x=55

    Divide each side by 11 and your answer is....

    x=5

  10. 6(3x - 5) - 7x = 25 (distributive property: x(a + b) = ax + bx)

    18x - 30 - 7x = 25 (combine like terms)

    11x - 30 = 25 (add 30 to both sides)

    11x = 55 (divide both sides by 11)

    x = 5 <===ANSWER
