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 - 9b = -3b - 2z + 7 for b in terms of z.
| \(\frac{7}{11}\)z - \(\frac{9}{11}\) | |
| z - \(\frac{8}{9}\) | |
| \(\frac{1}{5}\)z + \(\frac{3}{5}\) | |
| \(\frac{7}{9}\)z + \(\frac{7}{9}\) |
