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 -3b + 3b = -7b + 5z - 1 for b in terms of z.
| -1\(\frac{1}{5}\)z + 1\(\frac{3}{5}\) | |
| \(\frac{1}{18}\)z - \(\frac{1}{6}\) | |
| \(\frac{1}{2}\)z - \(\frac{1}{4}\) | |
| z - 4 |
