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