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