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