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 5a + 5a = 3a + 2z - 3 for a in terms of z.
| -1\(\frac{1}{2}\)z - 1\(\frac{1}{2}\) | |
| -\(\frac{1}{15}\)z + \(\frac{4}{15}\) | |
| -\(\frac{3}{14}\)z - \(\frac{1}{14}\) | |
| -9z - 6 |
