Solve the following equation
5x-16=x+4
Solve for x
5x - 16 = x + 4
Group variables
Group our variables 5x and x
subtract x from both sides
5x - 16 - x = x + 4 - x
Cancel x on the right side:
4x - 16 = 4
Divide each side by 5
| 5x | |
| 5 |
| = |
| -16 |
| 5 |
Group constants
Group our constants -16 and 4.
add 16 to both sides
4x - 16 + 16 = 4 + 16
Cancel 16 on the left side:
4x = 20
Divide each side of the equation by 4
| 4x | |
| 4 |
| = |
| 20 |
| 4 |
x = 5
Final Answer
x = 5
