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 4a - a = -6a + 2z + 2 for a in terms of z.
| 5z + 5 | |
| -\(\frac{8}{11}\)z - \(\frac{3}{11}\) | |
| z + 1 | |
| \(\frac{3}{10}\)z + \(\frac{1}{5}\) |
