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 6b + 2b = -9b - 7z - 7 for b in terms of z.
| -17z + 2 | |
| -\(\frac{3}{5}\)z - \(\frac{7}{15}\) | |
| -7z - 4\(\frac{1}{2}\) | |
| -1\(\frac{2}{5}\)z + 1\(\frac{3}{5}\) |
