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 -3b + 5b = -2b - 7z - 8 for b in terms of z.
| -1\(\frac{1}{7}\)z - 1 | |
| -2\(\frac{1}{2}\)z + 2 | |
| 12z + 8 | |
| 3z - 6 |
