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 = 8b + 9x + 3 for b in terms of x.
| -17x - 3 | |
| -\(\frac{6}{13}\)x + \(\frac{8}{13}\) | |
| -\(\frac{2}{3}\)x + 1\(\frac{1}{3}\) | |
| -x + \(\frac{4}{9}\) |
