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
The value of the x is 4.
Given that,
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
