<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.
