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 10b - 7b = 9b + 5x + 8 for b in terms of x.
| 3\(\frac{3}{4}\)x + 1\(\frac{1}{4}\) | |
| 12x + 8 | |
| 11x - 9 | |
| 2x - 7 |
