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 + 7a = -3a - 4y - 1 for a in terms of y.
| -\(\frac{10}{17}\)y - \(\frac{4}{17}\) | |
| 3\(\frac{2}{3}\)y + \(\frac{1}{3}\) | |
| -\(\frac{12}{13}\)y + \(\frac{9}{13}\) | |
| -\(\frac{1}{2}\)y + \(\frac{1}{4}\) |
