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 -5b - 7b = 5b + 5z + 2 for b in terms of z.
| -\(\frac{7}{8}\)z + \(\frac{7}{16}\) | |
| -\(\frac{2}{11}\)z - \(\frac{5}{11}\) | |
| -1\(\frac{1}{5}\)z - \(\frac{1}{5}\) | |
| -2\(\frac{1}{3}\)z - 2\(\frac{1}{3}\) |
