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 2a - 4a = -3a + 8z - 3 for a in terms of z.
| z - 4 | |
| 2z + 2 | |
| 12z - 2 | |
| 2\(\frac{2}{5}\)z - \(\frac{3}{5}\) |
