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