Question

if 2x+7y=34 and x+y=7 find valie of x and y​

Answer 1

Answer:

x=3 and y = 4

Step-by-step explanation:

Let X+ Y = 7 be X = 7- y

therefore 2x + 7y = 34

= 2( 7-y) + 7y = 34

14 - 2y + 7y = 34

14 + 5y = 34

5y = 34- 14

5y = 20

y= 20/5

y= 4

Now, x+ y = 7

= x +4 = 7

= x = 7-4

= x = 3
