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 + 6a = 3a + 7y - 3 for a in terms of y.
| \(\frac{10}{13}\)y + \(\frac{6}{13}\) | |
| -\(\frac{1}{2}\)y - \(\frac{2}{9}\) | |
| y + \(\frac{9}{14}\) | |
| -\(\frac{1}{10}\)y + \(\frac{3}{10}\) |
