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 5a + 7a = -9a - 3y + 2 for a in terms of y.
| -\(\frac{2}{9}\)y - \(\frac{1}{3}\) | |
| -1\(\frac{3}{8}\)y - \(\frac{3}{4}\) | |
| -\(\frac{12}{13}\)y + \(\frac{9}{13}\) | |
| -\(\frac{5}{7}\)y + \(\frac{1}{7}\) |
