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 -4b + 7b = -3b + 2y + 1 for b in terms of y.
| 5y - 1 | |
| 3y - 8 | |
| 1\(\frac{1}{2}\)y - 1\(\frac{1}{4}\) | |
| \(\frac{2}{13}\)y - \(\frac{7}{13}\) |
