______________________________
1.) Combine x and 3x:- We combine the
variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms.
2.) Add 19 to both sides:- We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals.
3.) Divide both sides by 4:- We do this to get x alone. To do this you do the opposite of what you see. In this case we have
which is multiplying, so you divide by 4 on each side.
So your answer is
.
