Question

Solve for x. x/5+ 1 = 7
x = 5 5/6
x = 30
x = 35
x = 40

Answer 1

Answer:

x = 30

Step-by-step explanation:

$\dfrac{x}{5}+1=7\qquad\text{subtract 1 from both sides}\\\\\dfrac{x}{5}+1-1=7-1\\\\\dfrac{x}{5}=6\qquad\text{multiply both sides by 5}\\\\5\!\!\!\!\diagup^1\cdot\dfrac{x}{5\!\!\!\!\diagup_1}=5\cdot6\\\\x=30$
