Answer:
D. x=5 and y = 11
Explanation:
we can take the unknown number to be x and the other number to be y. so
three times the number ie 3x is 7 less than two times the other number.
3x = 2y-7 (this expression say three times a number(x) is 7 less than two times the other number.
add 7 on both sides for the above eqn.
3x+7 = 2y-7+7
3x+7 = 2y;
four times the second number that is 4y is 44. or you can say 4y = 44
the y is 11. or y = 11.
if you put this y value in 3x+7 = 2y you get x =5
