Solve using substitution

Mathematics
1 answer:
mestny [16]3 years ago
8 0

Answer:

x=7, y=9. (7, 9).

Step-by-step explanation:

-3x+y=-12

5x-2y=17

---------------

y=-12-(-3x)

y=-12+3x

y=3x-12

5x-2(3x-12)=17

5x-6x+24=17

-x+24=17

-x=17-24

-x=-7

x=7

y=3(7)-12

y=21-12

y=9

step-by-step explanation:

The property to apply here is : congruent (corresponding alternate exterior and alternate interior angles) and supplementary (consecutive interior angles)

1.h = 180°-120°=60°=e=d=a

  f=120° = c=b

2.b=180°-105°=75°=c=f=g

   a=105°=e=h

3. f=180°-36°=144°=g=c=b

   a=36°=d=h

4. a=180°-161°=19°=e=h=d

   c=161°=f=g

5. f=180°-145°=35°=g=c=b

   a=145°=d=h

6. b=180°-25°=155°=c=f=g
