Success!
a=8
↓Steps Explained:↓
Solve for a
a + 16 = 3a
Group variables
Group our variables a and 3a
subtract 3a from both sides
a + 16 - 3a = 3a - 3a
Cancel 3a on the right side:
-2a + 16 = 0
Group constants
Group our constants 16 and 0.
subtract 16 from both sides
-2a + 16 - 16 = 0 - 16
Cancel 16 on the left side:
-2a = -16
Divide each side of the equation by -2
| -2a | |
| -2 |
| = |
| -16 |
| -2 |
a = 8
