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 - 4b = -8b + 3y - 2 for b in terms of y.
| 3y - 3 | |
| 7y - 2 | |
| \(\frac{5}{8}\)y + \(\frac{7}{8}\) | |
| 1\(\frac{1}{3}\)y + 2 |
