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

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
