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 + 6a = 8a - 7y - 1 for a in terms of y.
| 3\(\frac{1}{2}\)y + 2\(\frac{1}{2}\) | |
| 1\(\frac{2}{11}\)y + \(\frac{1}{11}\) | |
| 1\(\frac{1}{4}\)y - \(\frac{1}{4}\) | |
| \(\frac{1}{3}\)y - \(\frac{1}{3}\) |
