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 -7b + 3b = -8b - 7z - 6 for b in terms of z.
| -10z - 6 | |
| -5z + 7 | |
| -1\(\frac{1}{8}\)z + \(\frac{1}{8}\) | |
| 6z - 3\(\frac{1}{2}\) |
