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 -8a + 8a = -6a + 8z - 6 for a in terms of z.
| -\(\frac{1}{3}\)z - \(\frac{1}{2}\) | |
| z + 3 | |
| \(\frac{6}{7}\)z + \(\frac{6}{7}\) | |
| 2\(\frac{4}{5}\)z + 1\(\frac{2}{5}\) |
