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 - 2b = 2b + 7z + 5 for b in terms of z.
| \(\frac{1}{2}\)z + 1 | |
| -1\(\frac{4}{5}\)z - 1 | |
| \(\frac{1}{10}\)z + \(\frac{3}{5}\) | |
| -z + 4 |
