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 + 7b = -4b + 4z + 2 for b in terms of z.
| \(\frac{3}{13}\)z - \(\frac{9}{13}\) | |
| -2\(\frac{1}{2}\)z + 1\(\frac{1}{3}\) | |
| -\(\frac{5}{13}\)z - \(\frac{6}{13}\) | |
| -z + \(\frac{2}{3}\) |
