Answer:

x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.4(5x−12)+0.5x=15.2

(0.4)(5x)+(0.4)(−12)+0.5x=15.2(Distribute)

2x+−4.8+0.5x=15.2

(2x+0.5x)+(−4.8)=15.2(Combine Like Terms)

2.5x+−4.8=15.2

2.5x−4.8=15.2

Step 2: Add 4.8 to both sides.

2.5x−4.8+4.8=15.2+4.8

2.5x=20

Step 3: Divide both sides by 2.5.

2.5x

2.5

=
