When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -6a + 5a = 6a + 7z + 3 for a in terms of z.
| -\(\frac{1}{6}\)z - \(\frac{1}{4}\) | |
| z + \(\frac{9}{13}\) | |
| -5z + 3 | |
| 17z - 3 |
