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