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 - 8a = -3a + 2y - 3 for a in terms of y.
| 1\(\frac{1}{14}\)y - \(\frac{9}{14}\) | |
| 1\(\frac{2}{3}\)y - 2\(\frac{2}{3}\) | |
| \(\frac{1}{3}\)y + 1\(\frac{1}{3}\) | |
| 10y - 3 |
