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 3b + 7b = 2b - 6y - 5 for b in terms of y.
| -13y - 5 | |
| -\(\frac{10}{13}\)y - \(\frac{3}{13}\) | |
| 10y + 9 | |
| -\(\frac{2}{5}\)y + 1\(\frac{3}{5}\) |
