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