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