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 - 3 for a in terms of z.
| z - 3 | |
| -2z + 3 | |
| -13z - 5 | |
| \(\frac{1}{6}\)z - 1 |
