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 -2b + 6b = -3b + 8z - 5 for b in terms of z.
| 2\(\frac{1}{2}\)z - 1\(\frac{1}{2}\) | |
| \(\frac{6}{7}\)z + \(\frac{2}{7}\) | |
| -\(\frac{2}{11}\)z + \(\frac{4}{11}\) | |
| 2z - 5 |
