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 + [tex]\frac{5}{3}[/tex] = 65 [tex]\frac{2}{3}[/tex]
