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 -b + 3b = -8b - 7z - 3 for b in terms of z.
| -1\(\frac{3}{7}\)z - \(\frac{3}{7}\) | |
| -1\(\frac{1}{2}\)z + \(\frac{1}{2}\) | |
| -11z - 4 | |
| -2z + 5 |
