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