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 - 5b = 6b + 7z + 3 for b in terms of z.
| \(\frac{3}{13}\)z - \(\frac{4}{13}\) | |
| -\(\frac{1}{4}\)z - \(\frac{1}{3}\) | |
| -1\(\frac{5}{7}\)z - \(\frac{3}{7}\) | |
| -2\(\frac{4}{5}\)z - 1\(\frac{4}{5}\) |
