Question

What is X in 0.75x+12=21

Answer 1

Subtract 12 from both sides

0.75x = 21 - 12

Simplify 21 - 12 to 9

0.75x = 9

Divide both sides by 0.75

x = 9/0.75

Simplify 9/0.75 to 12

x = 12

Answer 2

x=12

Explanation:

0.75x+12=21

Subtract 12 from each side

0.75x+12-12=21-12

.75x = 9

Divide each side by .75

.75x/.75 = 9/.75

x = 12
