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 -4a + a = -7a - 2y - 8 for a in terms of y.
| -1\(\frac{2}{3}\)y + 2\(\frac{2}{3}\) | |
| \(\frac{2}{11}\)y + \(\frac{1}{11}\) | |
| -y - 2\(\frac{2}{3}\) | |
| -2y + \(\frac{1}{3}\) |
