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 + 7b = 7b - 3y - 5 for b in terms of y.
| -y - 1 | |
| -1\(\frac{2}{13}\)y + \(\frac{7}{13}\) | |
| -10y - 5 | |
| -\(\frac{3}{4}\)y - 1\(\frac{1}{2}\) |
