Question

Is the coordinate (1, 2) a solution of the system below?

x + 2y = 5

y = x + 1


Yes


No

Answer 1

(x, y) = (1, 2)

Replace the variables with the corresponding numbers. If they are both equal in the end, that is the solution:

1 + 2(2) = 5

2 = 1 + 1

Think you can do the rest? :3

Answer 2

is it yes or no

Answer 3

i think its yes

Answer 4

Yep. :3

1 + 2(2) = 5
1 + 4 = 5
5 = 5

2 = 1 + 1
2 = 2

Answer 5

okay thank you
