What is the complete solution of the equation
8  4x = 40 ? A.) x = 8 or x = 12 B.) x = 8 or x = 12 C.) x = 8 or x = 12 D.) x = 8 or x = 12 E.) x = 8
Absolute value is the distance away from zero.
This equation shows that (8  4x) is 40 away from zero. The two numbers that are 40 away from zero are 40 and 40. Therefore, (8  4x) could be 40, or (8  4x) could be 40. 8  4x = 40 8  4x = 40 or 8  4x = 40 {set (8  4x) equal to 40 and 40} 4x = 32 or 4x = 48 {subtracted 8 from each side of each equation} x = 8 or x = 12 {divided each side by 4} D.) x = 8 or x = 12 Ask Algebra House Comments are closed.
