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 3a - 5a = 2a - 3y + 6 for a in terms of y.
| 2y + 6 | |
| -\(\frac{1}{7}\)y + \(\frac{3}{7}\) | |
| \(\frac{15}{17}\)y + \(\frac{6}{17}\) | |
| \(\frac{3}{7}\)y + 1\(\frac{1}{7}\) |
