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