Answer:
Answer= 7
Step-by-step explanation:
the unknown number being, x, .
i think of a number ( x), double it, ( 2× x)= 2x, and add 11 to be ( 2x + 11), i get 25.
So, the equation will be:
2x + 11 = 25.
to solve it, take (+11) to the equals side and it will change to (-11), or in other words, subtract 11 on both sides.
the equation will thus remain to be:
2x = 25-11
2x = 14.................Divide both sides by 2 to remain with x
so, X = 7.
