7(3 - x) = 8(4 - 2x)?

Question

Solve for x

Answer 1

7(3-x)=8(4-2x)

21-7x=32-16x

9x=53

x=53/9

Answer 2

7(3-x)=8(4-2x)

21-7x=32-16x

16x-7x=32-21

9x=11

x=9/11

Answer 3

21 - 7x = 32 - 16x

9x = 11

x = 11/9

Answer 4

In case you want them, I am going to put in every step.

First multiply out the two sides of the equation.

21 - 7x = 32 - 16x    

Move the x terms to the left hand side of the equation

21 - 7x + 16x = 32    

Move the constant terms to the right hand side of the equation.

- 7x + 16x = 32 - 21

Combine like terms

9x = 11

Divide both sides of the equation by 9

x = 11/9  <<<<<

Answer 5

21-7x=32-16x then subtract 21 from both sides which gives you -7x=11-16x then add 16x to both sides and you get 9x=11 then you divide the nine from both sides and your answer would be x=11/9

Answer 6

Open up brackets first:

21 - 7x = 32 - 16x

Put x's on one side:

21 - 7x + 16x = 32

-7x + 16x = 32 - 21

9x = 11

x = 11/9

Answer 7

multiply 7 with each part inside parentheses

do the same for the other side of the equal side with 8

move x's to one side and numbers to the other

make x stand alone dividing the number side by the x-number

Answer 8

Hi,

For this question, we have to distribute the coefficients over the respective factors to get:

21 - 7x = 32 - 16x

Now, add 16x to both sides to get:

21 + 9x = 32

Now, subtract 21 from both sides to get:

9x = 11

At this point, we need x alone which is done by dividing both sides by 9 to get:

x = 11 / 9 <=== FINAL ANSWER

I hope that helps you out!  Please let me know if you have any other questions!

Answer 9

21-7x=32-16x

=> 9x=11 => x=11/9

Answer 10

21-7x=32-16x

+16x from both sides

21+9x=32

-21 from both sides

9x=11

x = 11/9
