Question

Find the value of x + y, if 5x - 2y = 4 and x + 8y = 26.​

Answer 1

Step-by-step explanation:

(eq. 1)

5x - 2y = 4

(eq. 2)

x + 8y = 26

adding eq. 1 & 2 :

5x -2y + x + 8y = 4+26

6x + 6y = 30

x = 30/6 = 5

x= 5

6y = 30

y= 30/6

y= 5

Value of : x+y = 5+5=10 ANSWER

Answer 2

Step-by-step explanation:

Given Find the value of x + y, if 5x - 2y = 4 and x + 8y = 26.

• 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
