X+5y=20
x+3y=14

x=
y=

y  = − 1 5 x + 4

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

according to egenuity the answer is
