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 = -4a + 4y - 4 for a in terms of y.
| \(\frac{3}{8}\)y + 1\(\frac{1}{8}\) | |
| y - \(\frac{1}{6}\) | |
| \(\frac{1}{11}\)y - \(\frac{4}{11}\) | |
| -\(\frac{4}{9}\)y + \(\frac{2}{9}\) |
