Question

find the value of x+y if 5x - 2y =4 and x + 8y = 26
solve the following. ​

Answer 1

Step-by-step explanation:

5x-2y=4

x+8y=26

Adding eq.1 and 2

5x-2y=4

x+8y=26

6x+6y=30

divide both side by 6

x+y=5

hope you get the right

Answer 2

Answer:

The value is x+y=5

Step-by-step explanation:

Given : Equations  5x - 2y =4 and x + 8y = 26

To find : The value of    x+y?

5x - 2y =4 ....(eq 1)

x + 8y = 26...(eq 2)

Substitute the value of x from (2) in (1),

5(26-8y) - 2y= 4

130- 40y  - 2y= 4

42y = 126

y= 126/24

y= 3

Substitute the value in (2),

x + 8 (3) = 26

x = 26 - 24

x =2

Now add the value of x and y,

x+y=2+3

x+y=5

Therefore , the value is x + y = 5

Substitute the value in (2),

Now add the value of x and y,

Therefore, the value is .
