4-5.

Write the equation represented by the diagram below. 4-5 HW eTool (CPM).

1. Simplify as much as possible and then solve for $x$.

Change all subtraction to addition and combine like terms.

Move the variable to one side of the equation.

$1+(−3)+2x=(−x)+(−3)+(−2)+(−x)$

$−2+2x=−2x+(−5)$

$−2+2x=−2x+(−5)$
$+2+2$

$2x=−2x+(−3)$

$2x=−2x+(−3)$
$+2x+2x$

$4x=−3$

$x=−0.75$

$1+(−3)−(−2x)=(−x)+(−3)−2−(x)$
