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