## Algebra: A Combined Approach (4th Edition)

$x=-7$
$10-(2x-4)=7-3x$ First, remove the parentheses by changing the sign of every term inside it: $10-2x+4=7-3x$ Substract $10$ to both sides of the equation $10-10-2x+4=7-3x-10$ $-2x+4=-3x-3$ Substract $4$ to both sides of the equation: $-2x+4-4=-3x-3-4$ $-2x=-3x-7$ To finally get the answer, add $3x$ to both sides of the equation: $-2x+3x=-3x+3x-7$ $x=-7$
