Question

Sum of two number is 775 and difference is 225 then find out the two numbers

Answer 1

Answer:

let the numbers are x and y

then ,

x+y=775

x-y=225

=> x=225+y

putting the value of x in above equation,

225+y+y=775

=> 2y=775-225

=> 2y=550

=> y=550/2

=> y=275

so, x=225+y=225+275=500

the numbers are 500 and 275

Answer 2

Answer:

x = 500 & y = 275

Step-by-step explanation:

let the two no .be Xand Y

x + y = 775

x = 775 - y (1 equation )

x - y =225

x = 225 +y ( 2 equation )

by 1 and 2 equation

775 - y = 225 + y

775 - 225 = y + y

550 = 2 y

y = 275

x = 775 - 275

x = 500
