Answer:
-4
Step-by-step explanation:
Given the expression 2(-2x-4)+6=5-3(x+1), we are to find the value of x that will make the expression true:
2(-2x-4)+6=5-3(x+1)
Open the parenthesis
2(-2x)-2(4)+6 = 5-3(x)-3
-4x-8+6 = 5-3x-3
Collect like terms
-4x-2 = -3x+2
Collect like terms
-4x+3x = 2+2
-x = 4
Divide both sides by -1
-x/-1 = 4/-1
x = -4
Hence the value of x that makes the equation true is -4
