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 - b = 9b + 5z - 7 for b in terms of z.
| z + 4 | |
| z - 1 | |
| -\(\frac{6}{13}\)z + \(\frac{7}{13}\) | |
| -\(\frac{3}{7}\)z + \(\frac{1}{2}\) |
