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 6b - 2b = -4b + 5z + 9 for b in terms of z.
| \(\frac{7}{10}\)z + \(\frac{9}{10}\) | |
| \(\frac{3}{8}\)z + \(\frac{1}{4}\) | |
| -1\(\frac{1}{3}\)z + 2 | |
| -1\(\frac{5}{6}\)z + \(\frac{1}{2}\) |
