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 + 2a = -5a + 5y - 2 for a in terms of y.
| \(\frac{1}{4}\)y - \(\frac{1}{6}\) | |
| \(\frac{4}{11}\)y - \(\frac{9}{11}\) | |
| \(\frac{7}{10}\)y + \(\frac{4}{5}\) | |
| \(\frac{5}{7}\)y - 1\(\frac{2}{7}\) |
