Question

Please someone help me with this question what is the x and y

Answer 1

Answer:

• x = -1
• y = 5

Solution:

• => 6x + 5y = 19

            -3x - 4y = -17

• => 6x + 5y = 19

           2(-3x - 4y = -17)

• => 6x + 5y = 19

           -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.
