Question

.Use the linear combination method to solve the system of equations. –3x + 8y = 16 3x + 4y = 8 What is the value of x?

Answer 1

0

Explanation:

Answer 2

The value of x is 0

Explanation:

The given equations are

`-3x+8y=16...(1)`

`3x+4y=8...(2)`

We add the equattion (1) and equation (2) to obtain;

`0x+12y=24`

`\Rightarrow y=(24)/(12)`

`\Rightarrow y=2`

We put
`y=2` into equation (2) to obtain;

`3x+4(2)=8`

`\Rightarrow 3x+8=8`

`\Rightarrow 3x=8-8`

Simplify

`\Rightarrow 3x=0`

Divide through by 3.

`\Rightarrow x=0`

The solution to the system is

`(0,2)`

The x-value is 0
