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