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 + b = 9b - 7z - 6 for b in terms of z.
| \(\frac{1}{5}\)z + \(\frac{2}{15}\) | |
| \(\frac{2}{3}\)z + \(\frac{1}{2}\) | |
| -\(\frac{1}{2}\)z + 3 | |
| -1\(\frac{1}{5}\)z + \(\frac{3}{5}\) |
