x=3
-3x + 8(-4x + 16) = 23
First, distribute the 8
-3x - 32x + 128 = 23
Simplify by combining like terms
-35x = -105
Divide
x = 3
Answer:
x=3
Step-by-step explanation:
−3x+8(−4x+16)=23
Step 1: Simplify both sides of the equation.
−3x+8(−4x+16)=23
−3x+(8)(−4x)+(8)(16)=23(Distribute)
−3x+−32x+128=23
(−3x+−32x)+(128)=23(Combine Like Terms)
−35x+128=23
−35x+128=23
Step 2: Subtract 128 from both sides.
−35x+128−128=23−128
−35x=−105
Step 3: Divide both sides by -35.
-35/-35 = -105/-35
x=3
