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 -7b - 7b = 5b - 2y + 5 for b in terms of y.
| -2y + 5 | |
| \(\frac{12}{13}\)y + \(\frac{7}{13}\) | |
| 1\(\frac{1}{5}\)y + \(\frac{1}{10}\) | |
| -\(\frac{5}{12}\)y - \(\frac{5}{12}\) |
