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