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
=
20
2.5
x=8
