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 -2b + 7b = 3b - 4x + 8 for b in terms of x.
| 2\(\frac{1}{5}\)x - 1\(\frac{3}{5}\) | |
| \(\frac{11}{17}\)x - \(\frac{3}{17}\) | |
| \(\frac{9}{11}\)x - \(\frac{4}{11}\) | |
| 4x - \(\frac{1}{2}\) |
