Answer:

a=60

Explanation:

Step 1: Simplify both sides of the equation.

0.18a+8.4=0.32a

Step 2: Subtract 0.32a from both sides.

0.18a+8.4−0.32a=0.32a−0.32a

−0.14a+8.4=0

Step 3: Subtract 8.4 from both sides.

−0.14a+8.4−8.4=0−8.4

−0.14a=−8.4

Step 4: Divide both sides by -0.14.

−0.14a ÷ −0.14 = −8.4 ÷ −0.14

a=60
