We must divide each equation by the coefficient (number multiplied to) the variable. This is because to solve equations, we need to get the variable alone on one side of the equation. If we divide each equation by the variable's coefficient, then this "undoes" the multiplication and cancels it out.
Therefore, you would:
A) Divide by -3
B) Divide by -4
C) Divide by -9
D) Divide by 4
Hope this helps!
