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

Answer:

The value of x is 0

Step-by-step explanation:

The given equations are

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

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

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

$0x+12y=24$

$\Rightarrow y=\frac{24}{12}$

$\Rightarrow y=2$

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

Answer 2
