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 -b + 4b = b - 7z + 7 for b in terms of z.
| \(\frac{1}{17}\)z + \(\frac{5}{17}\) | |
| 5\(\frac{1}{2}\)z - 3\(\frac{1}{2}\) | |
| -1\(\frac{3}{8}\)z - \(\frac{5}{8}\) | |
| -1\(\frac{3}{5}\)z + 1\(\frac{2}{5}\) |
