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