Answer:

x = (64 + 5) ÷ 3

Step-by-step explanation:

3x - 5 = 64

Add 5 to both sides: 3x = 64 + 5 = 69

Divide both sides by 3: x = 69 ÷ 3 = 23

So the answer is x = (64 + 5) ÷ 3

Note: If we didn't add the parentheses then using the order of operation x = 64 + 5 ÷ 3 would be x = 64 + $\frac{5}{3}$ = 65 $\frac{2}{3}$
