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