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 6a - 9a = -7a + 3y + 5 for a in terms of y.
| -2y + \(\frac{1}{3}\) | |
| \(\frac{12}{13}\)y + \(\frac{5}{13}\) | |
| 1\(\frac{1}{5}\)y + \(\frac{1}{2}\) | |
| -1\(\frac{1}{7}\)y - 1\(\frac{2}{7}\) |
