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 - 3a = -2a + 5z + 7 for a in terms of z.
| 1\(\frac{1}{3}\)z + 1\(\frac{1}{6}\) | |
| 1\(\frac{3}{5}\)z - 1 | |
| \(\frac{1}{6}\)z + \(\frac{3}{4}\) | |
| 1\(\frac{2}{9}\)z - \(\frac{2}{3}\) |
