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