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 = -4a + y + 6 for a in terms of y.
| 3y - 3 | |
| y - \(\frac{2}{3}\) | |
| -1\(\frac{5}{12}\)y - \(\frac{3}{4}\) | |
| \(\frac{1}{12}\)y - \(\frac{3}{4}\) |
