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 + 3b = 3b - 5x - 7 for b in terms of x.
| -5x - 6 | |
| -8x - 7 | |
| -6x + 7 | |
| 3\(\frac{2}{3}\)x - 1\(\frac{1}{3}\) |
