Question

Martin solved an equation, as shown below: Step 1: 19v = 76 Step 2: v = 76 - 19 Step 3: v =57 Part A: Is Martin's answer correct or incorrect? If it is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points) Part B: How many solutions will this equation have? (4 points)

Answer 1

A. incorrect. He has to divide 76 by 19, instead of subtract 19 to 76.

B. This equation has one solution. v=4

Explanation:

Hi, Martin’s answer is incorrect.

A. He has to divide 76 by 19, instead of subtract 19 to 76.

The correct steps are:

19v = 76

Since 19 is multiplying the variable, to eliminate it we have to divide by 19.

v = 76/19

v = 4

B. This equation has one solution. It’s v=4
