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 + 4a = -5a - 6y + 1 for a in terms of y.
| y - 1\(\frac{1}{2}\) | |
| y - 1\(\frac{1}{3}\) | |
| \(\frac{6}{7}\)y - \(\frac{1}{7}\) | |
| -\(\frac{5}{6}\)y + \(\frac{1}{12}\) |
