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 = 6b - 5x + 7 for b in terms of x.
| -x + 8 | |
| x - 1\(\frac{3}{4}\) | |
| \(\frac{2}{5}\)x - \(\frac{1}{3}\) | |
| -\(\frac{1}{2}\)x + \(\frac{3}{10}\) |
