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