Question

4
The
difference between two numbers is 17 and
their sum is 69. Find the largest of these two
number​

Answer 1

Answer:

Let one number be X and one number be Y

the sum of the two numbers is 17. Sum means addition.

Therefore, X+Y=17

difference means subtraction.

Twice larger=2X. Three times smaller=3Y

So, 2X-3Y=4

let’s review.

X+Y=17 and 2X-3Y=4

—

using elimination

first, let me multiply every term in the first system by 2

2[X+Y=17]. Distribute the two to get 2X+2Y=34

now let us subtract

2X + 2Y = 34

-2X -(-3Y) = -4

0 +5Y=30

we eliminated X to get 5Y=30

divide both sides by 5 to get Y=6

now, X+Y=17, so X+6=17. Subtract 6 from both sides and X=11

test.

2(11)-3(6)=22–18=4

therefore, X=11 and Y=
