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 -4b - 7b = -b - 4z + 7 for b in terms of z.
| \(\frac{4}{11}\)z + \(\frac{7}{11}\) | |
| z - \(\frac{2}{3}\) | |
| -z - 2\(\frac{1}{3}\) | |
| \(\frac{9}{14}\)z + \(\frac{3}{14}\) |
