x+y+2=0 and 3x+y-10=0 answer it with derivations and it's full method it's urgent..

Answers

Answered by ayushch

x-y+2=0
x= y-2 ...... Equation (1)

3x+y-10=0
putting x from Equation (1)
3(y-2)+y-10=0
3y-6+y-10=0
4y-16=0
4y=16
y=4 ....... Equation (2)

putting y from Equation(2) in Equation (1)
x= y-2 = 4-2 = 2
So. x= 4 & y= 2...

Ashimashibu: that's not the matter plz solve it plz

ayushch: yes of course ... i would love to help someone

ayushch: which one

Ashimashibu: it's wrong

ayushch: no , i have solved second one with respect to first one so the variables are just interchanged . but answer is correct

Ashimashibu: no x=2 and y =4 is the answer and the is correct given below

ayushch: i could solve again first Equation with respect to second but you've marked my answer brainiest how do i re answer it...

Ashimashibu: you can do here

ayushch: ok as you wish

ayushch: x-y+2=0. y=x+2 put y in 3x+y-10=0. 3x+x+2-10=0. 4x-8=0. 4x=8 x= 2. put x =2 in y=x+2 y=2+2 y= 4. So. x= 2 & y=4. See . i told you
