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 6a + 8a = 2a - 9y - 8 for a in terms of y.
| -4\(\frac{1}{4}\)y - 2 | |
| \(\frac{7}{18}\)y + \(\frac{1}{9}\) | |
| -4y + 2\(\frac{1}{2}\) | |
| -2\(\frac{1}{3}\)y + 2\(\frac{1}{3}\) |
