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 - 4b = -6b + 5z + 7 for b in terms of z.
| \(\frac{2}{11}\)z - \(\frac{8}{11}\) | |
| 3z + 3\(\frac{1}{2}\) | |
| \(\frac{5}{9}\)z - \(\frac{7}{9}\) | |
| 4\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) |
