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 3b + b = -b + 6x + 7 for b in terms of x.
| 1\(\frac{1}{4}\)x + 1\(\frac{3}{4}\) | |
| -\(\frac{5}{11}\)x + \(\frac{5}{11}\) | |
| -\(\frac{1}{9}\)x - \(\frac{7}{9}\) | |
| -x + \(\frac{1}{5}\) |
