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 -8b - 7b = -9b + 3z + 4 for b in terms of z.
| -15z + 5 | |
| -\(\frac{3}{4}\)z + \(\frac{3}{4}\) | |
| -\(\frac{3}{11}\)z + \(\frac{3}{11}\) | |
| 10z + 4 |
