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