This is some math i need help with ?

Question

1. Distribute on each side of the equation.

2. Collect like terms on each side of the equation.

3. Get all the variables on one side of the equation by doing the opposite math operation.

4. Solve for the variable.

8x - 1 = -4x + 23

x =

(2) 5x + 3 = 2x + 15

x =

(3) 5x + 2 = x + 10

x =

(4) 6x - 8 + 2x - 5 = 7 - 2x

x =

(5) 9(x - 2) = 3(x + 2)

x =

(6) 5(x + 4) = 7(x - 2)

x =

(7) 7(5x + 2) = 6(6x + 1)

x =

(8) 3(x + 6) - 2 = 4(x + 2) - 21

x =

(9) -2x - 18 = 6(1 - 2x) + 4x

x =

(10) Hint: When there is a minus sign in front of a parenthesis, you must distribute a -1. For example, the left side of the equation below would become 19 - 2x - 3 when you distribute.

19 - (2x + 3) = 2(x + 3) + x

x =

Answer 1

This is really quite easy. You basically have to rearrange the terms to get x= ... in each case.

Taking the first one:

8x-1=-4x+23

To get all the x on one side add 4x to each side

8x-1+4x=-4x+23+4x => 12x-1=23

Then 12x-1 +1 = 23 +1 => 12x=24

then divide by 12

12x/12=24/12 => x=2

Why don't you try some of the others.

Answer 2

i dont know if you want the workings shown, here are the complete answers

1 x=2

2. x=4

3 x=2

4 x=2

5 x=4

6 x=17

7 x=8

8 x=29

9 x=4

10 x=10

if you need the complete solution let me know

Answer 3

Is this something u need help with or something u want us to do?

Answer 4

I'll work one for you but you should do the rest on your own.

(6) 5(x+4) = 7(x-2)

    5(x) + 5(4) = 7(x) - 7(2)

    5x + 20 = 7x - 14

         +14   -5x

    34 = 2x

    x = 34/2

    x = 17
