solve the following questions

3x+4y=10 2x-2y=2

Answers

Answered by ADARSH9999

3x+4y = 10
2x -2y= 2

and here we can find it by six methods

but now we are going to solve it by elimination method
by equating their coefficient
3x+4y=10..........(i) 2x-2y=2 ...........(ii) ×2

we have to multiply with two in equation (ii)
then it will be

3x+4y=10
4x-4y=4
.......................
7x+0=14
7x=14
x=14/7
x=2

Now after putting the value of x in equation( i)

3×2+4y=10
6+4y=10
4y=4
y=1

x=2 and y=1

hope it helps you
if you are satisfied then plzz mark me as brainliest

I NEED IT SO MUCH

Piyusy: correct answer brainlieat

ADARSH9999: plzz mark me as brainliest mark me brainliest option present on top of my answer
