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 + 3a = -4a + 7y - 7 for a in terms of y.
| \(\frac{6}{17}\)y - \(\frac{8}{17}\) | |
| y - \(\frac{2}{3}\) | |
| \(\frac{2}{3}\)y - 1\(\frac{1}{6}\) | |
| \(\frac{6}{7}\)y + \(\frac{3}{14}\) |
