Question

WILL GIVE BRAINLIEST!! 20 POINTS

Answer 1

Answer:

We try to resolve the equations in our own to answer the question above. 

2x + y = 5

x − 2y = 10

y = 5 − 2x

x − 2(5 − 2x) = 10

x - 10 + 4x = 10

5x - 10 = 10

5x = 20

x = 4

Therefore, the correct answer among the choices is the second option. He did not distribute correctly.
