Question

What is the x-value of the solution to the system of equations below?
x+y +z = 8
x + 2y = 6
y +z = 4

Answer 1

Answer:

Let's solve for x.

x+y+z=8

Step 1: Add -y to both sides.

x+y+z+−y=8+−y

x+z=−y+8

Step 2: Add -z to both sides.

x+z+−z=−y+8+−z

x=−y−z+8

Answer:

x=−y−z+8

Answer 2

The value of the x is 4.

Given that,

• The equations are x+y +z = 8 , x + 2y = 6 , and y +z = 4.

Based on the above information, the calculation is as follows:

x + y + z = 8

y + z = 4

So,

x + 4 = 8

x = 8 - 4

= 4
