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 4a - 4a = -7a + 5z - 2 for a in terms of z.
| -4\(\frac{1}{3}\)z + 1 | |
| \(\frac{9}{11}\)z - \(\frac{2}{11}\) | |
| -z - 1\(\frac{2}{7}\) | |
| -8\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) |
