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