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