Question

the sum of 2 nos.is 8.if their sum is 4 times their difference ,find the nos
​

Answer 1

Step-by-step explanation:

let one number be X and second number be Y

now, According to the question,

X + Y = 8

X = 8 - Y........eq 1

it is given that their sum is 4 times their difference .

8 * 4 = X - Y

32 = X - Y

X= 32 + Y .........eq 2

now substituting the Value of X from eq 1 in eq 2

8 - Y = 32 + Y

Y + Y = 8- 32

2Y = -24

Y = -12

now by substituting the value of Y = -12 ... you can find X.
