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 + 6b = 7b + 8z - 6 for b in terms of z.
| -\(\frac{1}{2}\)z - 3\(\frac{1}{2}\) | |
| -\(\frac{2}{11}\)z + \(\frac{6}{11}\) | |
| -\(\frac{9}{16}\)z - \(\frac{1}{16}\) | |
| 1\(\frac{1}{9}\)z - \(\frac{1}{9}\) |
