Question

Solve for x
-4x -3 = -12x - 23

Answer 1

-10/4

Explanation:

collect the like terms on one side such that you have the values of x on one side,simplify then divide both sides by the coefficient of x to find it's value

Answer 2

-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
