Question

Malloy solved the equation-5x-16=8 his work is shown below. Identity the error and where it was made. Step 1: -5x-16+16=8+16 Step 2: -5x=24 Step 3: -5x/5=24/5 Step 4: x=24/5

Answer 1

he divided both sides by 5 instead of -5 in his last step

Explanation:

Given the expression solved by max expressed as;

-5x - 16 = 8

Step 1: Add 16 to both sides

-5x - 16 + 16 = 8 + 16

-5x = 24

Step 2:

Divide both sides by -5

-5x/-5 = 24/-5

x = -24/5

According to Malloy calculation, he divided both sides by 5 instead of -5 in his last step
