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