Is the equation
4x - 16y = 8
x - 4y = 4
no solution?

Step-by-step explanation:

this system has no solutions,

we divide first equation by 4

x-4y=2

x-4y=4

4 not equal to 2

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
