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