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 + 9b = -9b + 7z + 6 for b in terms of z.
| 4\(\frac{1}{3}\)z - 1 | |
| -\(\frac{1}{4}\)z + \(\frac{3}{4}\) | |
| 10z + 3 | |
| -1\(\frac{3}{10}\)z + \(\frac{7}{10}\) |
