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