if x+y=5 then the sum of 13x + 22y and 17x + 8y is??
Answers
Answer:
13x+22y+17x+8y
30x+30y
30(x+y)
As,
x+y=5
Then,30(x+y)=30*5
=150
The value of sum of equation 13 x + 22 y and 17 x + 8 y is 150 .
Step-by-step explanation:
Given as :
The sum of x and y = 5
i.e x + y = 5 ...........1
Two linear equation are
13 x + 22 y .........2
17 x + 8 y ..........3
Let The sum of equation 13 x + 22 y and 17 x + 8 y = A
According to question
The sum of equation 13 x + 22 y and 17 x + 8 y = ( 13 x + 22 y ) + ( 17 x + 8 y )
From eq 2 and eq 3
Or, A = ( 13 x + 22 y ) + ( 17 x + 8 y )
Or, A = ( 13 x + 17 x ) + ( 22 y + 8 y )
Or, A = 30 x + 30 y
Now, Taking 30 as common
i.e , A = 30 ( x + y )
Or, A = 30 × ( 5 ) (from eq 1)
∴ A = 150
So, The value of sum of 13 x + 22 y and 17 x + 8 y = A = 150
Hence, The value of sum of equation 13 x + 22 y and 17 x + 8 y is 150 . Answer
