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