The point (2,1) is a solution to which of the following systems of equations

x+y = 3

3x-y = 5

Step-by-step explanation:

x+y = 3

3x-y = 5

This system of equation will give the points(2,1).

Lets substitute the values x=2 and y = 1 in the equations:

x+y=3    equation 1

2+1 =3

3=3

3x-y=5  equation 2

3(2)-1=5

6-1=5

5=5

Lets solve the system:

Add the equations to eliminate y from the system:

x+y = 3

3x-y = 5

4x    = 8

Now divide both the sides by 4

4x/4 = 8/4

x=2

Now substitute the value of x in equation 1:

x+y=3

2+y=3

Combine the constants:

y=3-2

y=1
