Answer: 1. 2y+x=5, 5x-y=3 or y-5x=3 and 2. y=x-3 or y=3-x, y=1/3(x+9)
Step-by-step explanation:
In first question, x represent the smaller number and y represent the larger number.
And, Twice a number added to a smaller number is 5.
That is, 2×larger number + smaller number = 5
⇒2y+x=5,
Moreover, The difference of 5 times the smaller number and the larger number is 3.
that is, 5× smaller - larger = 3 or larger - 5× smaller = 3
⇒ 5x - y =3 or y - 5x =3
In second question,
y represents the smaller number and x represents larger number.
And, A number, y, is equal to the difference of a larger number and 3.
That is, y= x -3 or y= 3- x
Moreover, The same number is one-third of the sum of the larger number and 9.
⇒ y = 1/3(x+9)
