Consider this solution to a problem.
Problem: 4(6  y) + 4 = 4 Step 1: 24  4y + 4 = 4 Step 2: 20  4y = 4 Step 3: 4y = 16 Step 4: y = 4 Choose the number of the step where the first mistake was made. Then, solve the equation correctly.
The first mistake was made in Step 1, by not distributing the 4 correctly.
Step 1 should read: 24 + 4y + 4 = 4 Correct steps and solution: 4(6  y) + 4 = 4 24 + 4y + 4 = 4 {used distributive property with 4} 4y  20 = 4 {combined like terms} 4y = 16 {added 20 to each side} y = 4 {divided each side by 4} Ask Algebra House Comments are closed.
