Question

Y-8/5 = 3 solve for y a. 23 b. 7 c. -7 d. -23

Answer 1

Answer:

$\large\boxed{a.\ 23}$

Step-by-step explanation:

$\dfrac{y-8}{5}=3\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{y-8}{5\!\!\!\!\diagup_1}=5\cdot3\\\\y-8=15\qquad\text{add 8 to both sides}\\\\y-8+8=15+8\\\\y=23$
