What’s x ? And what’s y ?

Step-by-step explanation:

Given

x = 2y

And

-4x + 11y = 15

- 4 * 2y + 11y = 15

-8y + 11y = 15

3y = 15

Therefore y = 5

Now putting y = 5

x = 2* 5

= 10

i hope this helps

all answers

Step-by-step explanation:

all of them actually

x - 37 = x - 37

add 37 to both sides   x = x

take x from both sides   0 = 0 so infinite amount of answers

73x - 37 = 73x - 37

add 37 to both sides   73x = 73x

take 73x from both sides   0 = 0   so again infinite amount of answers

37x - 37 = 37x - 37

add 37 to both sides   37x = 37x

take 37x from both sides   0 = 0 once again infinite amount of answers

74x - 37 = 74x - 37

add 37 to both sides   74x = 74x

take 74 from both sides   0 = 0 and finally infinite amount of answers could be as x
