Question

Find the value of x & y , if 3x+2y=2 & 10x=5+5y​

Answer 1

Answer:

3x+2y=2 & 10x=5+5y

3x+2y=2........….१

10x-5y=5 => 2x-y=1 ..........२

put out y from eq २

y=2x-1

put y in eq१

3x+2y=2

3x+2(2x-1)=2

3x+4x-2=2

7x=4

x=4/7

put x=4/7 in y =2x-1

y= 2×4/7 -1

y= 8 / 7-1

y= 8-7 / 7

y=1/7
