Question

What is the value of the y variable in the solution to the following system of equations?

3x + y = 14

-3x + 2y = 1

5
3
y can be any number as there are infinitely many solutions to the system.
There is no y value as there is no solution to the system.

I don't see my problem on there what's the answer

Answer 4

I put you an example. So YOU could solve your problem. And if you get stuck I could help you : )

Answer 5

Ok

Answer 6

I can tell you how to solve two equation with two variables

Answer 7

I got 3 for my answer

Answer 8

\[\large \bf 3x+y=14................(1)\]
\[\large \bf -3x+2y=1..............(2)\]

From equation (1),
\[\large \bf y=14-3x.........................(3)\]

now put equation (3) in equation (2),
\[\large \bf -3x+2(14-3x)=1\]
\[\large \bf -3x+28-6x=1\]
\[\large \bf -9x=-27\]
so,
\[\large \bf x=3\]

Now,put the value of x=3 in the equation (3) and then find the value of y,
\[\large \bf y=14-3(3)=14-9=5\]

So,we get
\[\large \bf x=3~and~y=5~as~\color{red}{Answers}\]
