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 = -5a - 3y + 4 for a in terms of y.
| -1\(\frac{5}{8}\)y - \(\frac{3}{4}\) | |
| 3y + 6 | |
| \(\frac{4}{11}\)y + \(\frac{4}{11}\) | |
| -\(\frac{2}{17}\)y + \(\frac{4}{17}\) |
