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