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 a + 8a = -2a + 3y + 6 for a in terms of y.
| \(\frac{5}{14}\)y - \(\frac{5}{14}\) | |
| -\(\frac{2}{7}\)y - 1\(\frac{2}{7}\) | |
| -1\(\frac{2}{3}\)y + 2 | |
| 6y + 1 |
