Question

x+2y=7 2x+y=8 how to sollow this problem

Answer 1

Answer:

They are not equal.

Step-by-step explanation:

We'll do 2x + y first.

2x + y = 8

x + y = 8/2 = 4

X and y  are different numbers, if they were different, both numbers would be labelled as x or y. The number combinations to get 4 is, 2 + 2 or 1 + 3 .

x = 1

y = 3

x + 2y = 7

1 + (2 x 3) = 7

1 + 6 = 7

But,

2x + y ≠ 8

(2 x 1) + 3 = 8

2 + 3 ≠ 8

{≠ means, it is not equal to }

So therefore, x + 2y = 7 and 2x + y = 8, are not equal.
