Answer:
-2.5
Explanation:
−4x−3=−12x−23
Add 12x to both sides.
−4x−3+12x=−23
Combine −4x and 12x to get 8x.
8x−3=−23
Add 3 to both sides.
8x=−23+3
Add −23 and 3 to get −20.
8x=−20
Divide both sides by 8.
x= −20/8
Reduce the fraction to lowest terms by extracting and canceling out 4.
−20/8
x=−5/2decimal = -2.5
