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