Question

in x+y=83 and 4x+y=178. Find the value of x and y using elimination method

Answer 1

give a write questions wrong answer correct it please .....

Answer 2

from first question we know that
x+y=83
by elimination method
we should multiply the whole equation by 4
now we get
4x+4y= 332......1
4x+y =178.......2
interchange the sign

the term 4x sould cancel
3y=154
y=51.111
what the value of Y and equation
4x+y=178
4x+51.1=178
4x=126.9
x=31.8 andwer..
