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 + 5a = -5a - 9y + 2 for a in terms of y.
| -\(\frac{6}{7}\)y - \(\frac{4}{7}\) | |
| -2\(\frac{1}{3}\)y + \(\frac{1}{3}\) | |
| -\(\frac{1}{7}\)y + \(\frac{2}{7}\) | |
| -1\(\frac{1}{4}\)y + 2 |
