Question

-1/2x+3=-x+7
I just don't know how to take the fraction out :(

Answer 1

x = 8

Explanation:

`- (1)/(2) x + 3 = - x + 7`

Collect like terms and simplify

`- (1)/(2) x + x = 7 - 3 \\ (1)/(2) x = 4`

Cross Multiply

`x * 1 = 2 * 4 \\ x = 8`

Answer 2

x = 8

Explanation:

-1/2x+3=-x+7

Add x to each side

-1/2x+x+3=-x+x+7

1/2x+3=7

Subtract 3 from each side

1/2x +3-3=7-3

1/2x=4

Multiply by 2

1/2x*2 = 4*2

x = 8
