Find x and y x=2y-6 x+2y=7

y=      x=

Step-by-step explanation:

x=2y-6 x+2y=7

2y-6 +2y=7

4y-6=7

4y=13

y=

x=2y-6

x=2()-6

x=-6

x=

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

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
