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