Question

Write the solution of the equation 2x + y = 5 a) (0,2) b) (3,2) c) (-1,3) d) (1,3)​

Answer 1

Answer:

Correct option is

C

(1,3)

We have to check whether these pairs satisfy equation 2x+y=7 or not.

So, we will put these pairs one by one.

A) (1,5)⇒2×1+5=7 so, it satisfies.

B) (3,1)⇒2×3+1=7 so, it satisfies.

C) (1,3)⇒2×1+3=5 so, it does not satisfies.

D) (1,5)⇒2×0+7=7 so, it satisfies.

Option C is the correct option.

Step-by-step explanation:

Correct option is

B

x=5, y=0

2x + y = 10

Let x = 5

then, 10+ y = 10

y = 0

Hence, the solution of the equation is (5,0)

Answer 2

Answer:

c) will be the answer cuz we have to check whether these pairs are satisfied equation or not

Step-by-step explanation:

A) (1,5) = 2×1+5=7 so, it satisfies

B) (3,1)⇒2×3+1=7 so, it satisfies.

C) (1,3)⇒2×1+3=5 so, it does not satisfies

D) (1,5)⇒2×0+7=7 so, it satisfies.
