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 + 8b = -5b - 6z + 4 for b in terms of z.
| -2z + \(\frac{4}{7}\) | |
| \(\frac{13}{17}\)z - \(\frac{8}{17}\) | |
| -4z - 3\(\frac{1}{2}\) | |
| -\(\frac{5}{7}\)z + \(\frac{3}{14}\) |
