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 3a + 4a = 6a - 2y + 7 for a in terms of y.
| -1\(\frac{1}{2}\)y + \(\frac{2}{5}\) | |
| -13y + 3 | |
| 2y - 2\(\frac{1}{3}\) | |
| -3y - \(\frac{2}{5}\) |
