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 a - 4a = -3a + 7y + 1 for a in terms of y.
| 2\(\frac{3}{4}\)y + \(\frac{1}{4}\) | |
| -\(\frac{6}{11}\)y + \(\frac{4}{11}\) | |
| -1\(\frac{1}{12}\)y - \(\frac{3}{4}\) | |
| -1\(\frac{1}{14}\)y + \(\frac{3}{7}\) |
