Question

solve : x+y = 5 and 3x -y = 7​

Answer 1

Answer:

X=3,y=2

Step-by-step explanation:

X+y=5

Y=5-x

Put y=5-x in 3x-y=7

3x-y=7

3x-(5-x)=7

3x-5+x=7

4x=7+5=12

X=12/4=3

x+y=5

3+y=5

Y=2

Answer 2

Answer:

x=3,y=2

Step-by-step explanation:

First find y in terms of x

y=-x+5

Now substitute into the second equation

3x-(-x+5)=7

3x+x-5=7

4x=7+5=12

x=12/4=3

Now the value of y will be

3+y=5

y=5-3=2

Hence found the solution
