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 + 2b = 8b - 4x - 1 for b in terms of x.
| -\(\frac{8}{13}\)x - \(\frac{6}{13}\) | |
| -\(\frac{4}{17}\)x + \(\frac{7}{17}\) | |
| 2\(\frac{3}{4}\)x - 1 | |
| \(\frac{2}{5}\)x + \(\frac{1}{15}\) |
