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 + a = -4a - 3y + 7 for a in terms of y.
| \(\frac{5}{8}\)y + \(\frac{3}{16}\) | |
| -\(\frac{1}{3}\)y - \(\frac{1}{3}\) | |
| y - 1\(\frac{1}{5}\) | |
| 2y - 3\(\frac{1}{2}\) |
