Solve the equation. Check for extraneous solutions. 4x = 28 Absolute value is the distance away from zero. 4x = 28 4x = 28 or 4x = 28 {the two numbers that are 28 away from zero are 28 and 28} x = 7 or x = 7 {divided each side by 4} Check. If it makes a false statement, then it is an extraneous solution. Check 7: 4(7) = 28 28 = 28 {multiplied} 28 = 28 {true statement, so 7 is not extraneous} Check 7: 4(7) = 28 28 = 28 {multiplied} 28 = 28 {a true statement, so 7 is not extraneous}  Algebra House
