Question

sum if 2 numbers is 145 and difference is 55 find the numbers​

Answer 1

Answer:

★$\huge{\underline{\mathfrak{Answer\::}}}$

$\rule{300}{2}$

Let the first number be X

[X>Y]

And the other number be Y

First equation:-

X + Y = 145

★$\implies$X = 145 - Y..............(i)

Second equation:-

X - Y = 55

★$\implies$X = Y + 55...........(ii)

Putting the value of (i) here,

$\rule{300}{2}$

145 - Y = Y + 55

$\implies$-Y-Y = 55 - 145

$\implies$-2Y = -90

$\implies$Y = -90/-2

★$\implies$Y = 45

Putting the value of Y in (ii) equation,

$\rule{300}{2}$

X = 45 + 55

★ $\implies$X = 100

So two numbers are 100 and 45

Answer 2

Answer:

y = 45 and x = 100

Step-by-step explanation:

hear, Let the number be x and y

Then x + y = 145 --(1)

x - y = 55----(2)

Adding (1) and (2) we get

2x = 200

x = 100

y = 145 - x

y = 45
