Answer:

(3,3)

x=3 and y=3

Step-by-step explanation:

The system of equations are:-

3x - y = 6

6x + y = 21

Elimination method: To eliminate one variable by add/sub both equation and solve for another variable.

3x - y = 6

6x + y = 21

Add both equation and eliminate y

3x + 6x = 6 + 21

       9x = 27

          x = 3

Put x=3 into 6x + y = 21

6(3) + y = 21

18 + y = 21

      y = 21 - 18

      y = 3

Hence, The solution of the system of equations is (3,3)

Answer:  The two triangles are similar because the angles are congruent.

Step-by-step explanation: If you add the given measures of the angles given, then subtract from 180, the remainder is equal to the measure of the angle given for the other triangle.

180 - (103 + 22) = 55

180 - (22 + 55)  = 103

So both triangles have the same angle measurements.
