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 -3a + 10a = 8a - 9z + 3 for a in terms of z.
| \(\frac{5}{7}\)z - \(\frac{5}{7}\) | |
| 1\(\frac{8}{11}\)z - \(\frac{3}{11}\) | |
| -\(\frac{1}{12}\)z - \(\frac{2}{3}\) | |
| 3\(\frac{1}{4}\)z - 2 |
