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 -2b + 7b = -b + 8z + 6 for b in terms of z.
| 1\(\frac{3}{4}\)z + \(\frac{1}{2}\) | |
| -\(\frac{3}{11}\)z + \(\frac{7}{11}\) | |
| -\(\frac{10}{11}\)z + \(\frac{3}{11}\) | |
| -z - 6 |
