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 -7a - 3a = -a - 8y - 8 for a in terms of y.
| \(\frac{5}{11}\)y - \(\frac{6}{11}\) | |
| \(\frac{5}{6}\)y + 1\(\frac{1}{3}\) | |
| y + 1\(\frac{1}{5}\) | |
| \(\frac{3}{5}\)y + \(\frac{8}{15}\) |
