Question

Solve the system

x+3y=5
x+4y=6

A) (2,1)
B) (1,5)
C) (8,-1)
D (11,-2)

Answer 1

So you have the equations
x + 4y = 6
x + 3y = 5
Subtract the two equations.

You get y = 1.
The only answer with a value of y = 1 is A

A is your answer.
Have a nice day! :)

Answer 2

A(2,1)

Explanation:

We are given that system of equation

`x+3y=5`

`x+4y=6`

We have to solve the system

Subtract equation first from equation second

Then, we get

`y=1`

Substitute the value of y in equation I

Then, we get

`x+3(1)=5`

`x=5-3=2`

Hence, the option A is true.

Answer:A(2,1)
