Question

without finding the value of x and y.find the value of x +y; if x+2y=27 and 2x +y=33

Answer 1

Adding both equations

x+2y+2x+y=27+33

3(x+y)=60

x+y=20

Answer 2

Answer:

20

Step-by-step explanation:

Add the two equations...

x + 2y=27

2x + y=33

Therefore,

3x+3y=60

Dividing bboth sides of the equation by 3,

x+y=20
