I dont know the answers to this question please tell me the x and y
Eddi Din [679]

<u>Answer:</u>

  • x = -5
  • y = 5

<u>Step-by-step explanation:</u>

  • => -7x - 2y = 25

            -4x - 9y = -25

  • => 4(-7x - 2y = 25)

             7(-4x - 9y = -25)

  • => -28x - 8y = 100

            -28x - 63y = -175

  • => 55y = 275
  • => y = 5

<u>Now, let's substitute the value of y into the first equation.</u>

  • => -7x - 2y = 25
  • => -7x - 2(5) = 25
  • => -7x - 10 = 25
  • => -7x = 35
  • => x = -5

<u>Now, let's check our answer to make sure our answer is correct.</u>

<u>Check:</u>

  • -4x - 9y = -25
  • => -4(-5) - 9(5) = -25
  • => 20 - 45 = -25
  • => -25 = -25

Hence, this is proved correct.

Hoped this helped.
