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