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 b + 8b = 7b + 3x + 7 for b in terms of x.
| -1\(\frac{4}{7}\)x - \(\frac{3}{7}\) | |
| \(\frac{5}{6}\)x - 1\(\frac{1}{6}\) | |
| -\(\frac{1}{6}\)x + 1 | |
| \(\frac{9}{10}\)x + \(\frac{3}{5}\) |
