Question

give me the solution​

Answer 1

Answer:

x + y = 5

Step-by-step explanation:

We have the equation as

5x – 2y – 4 = 0 ---------------1

x + 8y – 26 = 0 --------------2

Multiply equation 2 by 5 so we get

5x – 2y – 4 = 0

5x + 40y – 130 = 0

Subtracting both equations we get

    -42 y + 126 = 0

Or 42 y = 126

Or y = 3

Substituting y = 3 in equation 1 we get

5x – 2(3) = 4

5x – 6 = 4

5x = 10

Or x = 2

So x + y = 2 + 3 = 5
