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 + 7a = a - 4y + 5 for a in terms of y.
| 1\(\frac{1}{8}\)y - \(\frac{1}{2}\) | |
| -17y + 6 | |
| -\(\frac{1}{2}\)y - 3 | |
| 2\(\frac{3}{4}\)y - 1\(\frac{1}{4}\) |
