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 -b - 7b = 3b + 4z - 3 for b in terms of z.
| -5z + 8 | |
| -10z + 4 | |
| -\(\frac{1}{13}\)z + \(\frac{5}{13}\) | |
| -2\(\frac{3}{4}\)z + \(\frac{3}{4}\) |
