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 7a + 6a = -a + 6z + 5 for a in terms of z.
| z - 1 | |
| 4z + 2 | |
| z + \(\frac{5}{8}\) | |
| \(\frac{1}{2}\)z - 1 |
