Question

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

4x + 2y = 6
x – y = 3

−1
5
−2
2

Answer 1

For the first set of equations, the value of y in the solution is -2.
For the second set of equations, the value of x in the solution cannot be solved because they have the same slope.
solve x and y values.
For the third set of equations, the value of x in the solution is 3.

Answer 2

`x=2`

Explanation:

we have

`4x+2y=6` -----> equation A

`x-y=3`

Isolate the variable y

`y=x-3` -----> equation B

Substitute the equation B in the equation A and solve for x

`4x+2(x-3)=6`

`4x+2x-6=6`

`6x=12`

`x=2`
