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 = 7a - 2z - 6 for a in terms of z.
| -z - 1 | |
| -7z - 3 | |
| -\(\frac{5}{12}\)z - \(\frac{1}{4}\) | |
| 7z + 6 |
