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 - 2a = -9a - y - 8 for a in terms of y.
| 2\(\frac{1}{7}\)y + \(\frac{5}{7}\) | |
| 8y + 3 | |
| -1\(\frac{3}{5}\)y - \(\frac{3}{5}\) | |
| \(\frac{1}{6}\)y - 1\(\frac{1}{3}\) |
