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 -9a + a = 2a - 4y + 3 for a in terms of y.
| -\(\frac{6}{7}\)y + \(\frac{1}{2}\) | |
| -\(\frac{1}{3}\)y - 1\(\frac{1}{6}\) | |
| 8y - 4\(\frac{1}{2}\) | |
| \(\frac{5}{11}\)y - \(\frac{3}{11}\) |
