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 -6b + 4b = -7b + 2y + 7 for b in terms of y.
| -2y + 7 | |
| y + 2 | |
| -3y - 2 | |
| -1\(\frac{1}{2}\)y - 1 |
