Answer:
Solution:
-3x - 4y = -17
2(-3x - 4y = -17)
-6x - 8y = -34
- => -3y = -15
- => 3y = 15
- => y = 5
Now, let's take one equation and substitute the value of y in it.
- 6x + 5y = 19
- => 6x + 5(5) = 19
- => 6x + 25 = 19
- => 6x = 19 - 25
- => 6x = -6
- => x = -1
Check:
- => -3x - 4y = -17
- => -3(-1) - 4(5) = -17
- => 3 - 20 = -17
- => -17 = -17
Hence, this is proven correct.
Hoped this helped.
