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 2a + 2a = a + 8y - 2 for a in terms of y.
| 6y - 2 | |
| \(\frac{5}{8}\)y + \(\frac{5}{8}\) | |
| \(\frac{1}{3}\)y - \(\frac{1}{3}\) | |
| -\(\frac{4}{15}\)y + \(\frac{4}{15}\) |
