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 = -6a - 9y + 8 for a in terms of y.
| -\(\frac{1}{4}\)y - \(\frac{3}{4}\) | |
| 5y - 2 | |
| -1\(\frac{3}{4}\)y - 1 | |
| 15y - 8 |
