Answer:
Answer:
x=−27
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.4(5x−15)=2.5(x+3)
(0.4)(5x)+(0.4)(−15)=(2.5)(x)+(2.5)(3)(Distribute)
2x+−6=2.5x+7.5
2x−6=2.5x+7.5
Step 2: Subtract 2.5x from both sides.
2x−6−2.5x=2.5x+7.5−2.5x
−0.5x−6=7.5
Step 3: Add 6 to both sides.
−0.5x−6+6=7.5+6
−0.5x=13.5
Step 4: Divide both sides by -0.5.
−0.5x
−0.5
=
13.5
−0.5
x=−27
