Question

find the solution of x+y=10, x-y=5​

Answer 1

$\huge\sf\underline\purple{Solution}$

Given 2 equations We have to add the two equations We can get value of x,y

x + y =10

x - y = 5

_______

2x = 15

________

x = $\frac{15}{2}$

x + y = 10

$\frac{15}{2}$ + y = 10

y = $\frac{15}{2}$ - 10

y = $\frac{-20+15}{2}$

y = $\frac{-5}{2}$

Therefore values of x and y are $\frac{15}{2}$ and $\frac{-5}{2}$
