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 + b = -5b - 2x + 4 for b in terms of x.
| \(\frac{1}{3}\)x + \(\frac{8}{9}\) | |
| x + 1 | |
| -x + 1\(\frac{1}{3}\) | |
| x + \(\frac{2}{5}\) |
