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 - 3a = a + 6y + 5 for a in terms of y.
| 4\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| -\(\frac{1}{9}\)y + \(\frac{8}{9}\) | |
| 1\(\frac{4}{7}\)y + \(\frac{4}{7}\) | |
| \(\frac{4}{7}\)y - 1 |
