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 + 2b = 9b - 3z - 8 for b in terms of z.
| \(\frac{5}{7}\)z + 1\(\frac{1}{7}\) | |
| -2\(\frac{2}{3}\)z - \(\frac{1}{3}\) | |
| \(\frac{5}{13}\)z - \(\frac{1}{13}\) | |
| \(\frac{3}{4}\)z - \(\frac{1}{2}\) |
