Answer 2

step by step :

4-(x-1)=7-2x

4-x+1=7-2x

add the number

5-x=7-2x

Rearrange terms

-x+5=7-2x

Rearrange terms

-x+5=-2x+7

Subtract from both sides of the equation

-x+5-5=-2x+7-5

Subtract the numbers

−x=-2x+2

Add 2x to both sides of the equation

-x+2x=-2x+2+2x

Combine like terms

Multiply by 1

x=2
