Question

Solve the system x+3y=5 x+4y=6 A) (2,1) B) (1,5) C) (8,-1) D (11,-2)

Answer 1

Answer:

A(2,1)

Step-by-step 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)

Answer 2

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! :)
