Question

Solve for x 8 + x/3 = 15

Answer 1

Answer:

x = 21

Step-by-step explanation:

subtract 8 from both sides

you get x/3 = 7

multiply both sides by 3 you get x=21

Answer 2

Answer:

x = 21

Step-by-step explanation:

$8+\dfrac{x}{3}=15\qquad\text{multiply both sides by 3}\\\\(3)(8)+3\!\!\!\!\diagup^1\cdot\dfrac{x}{3\!\!\!\!\diagup_1}=(3)(15)\\\\24+x=45\qquad\text{subtract 24 from both sides}\\\\24-24+x=45-24\\\\x=21$
