Answer:
x = 67
Step-by-step explanation:
Here it is given that,
- x is an unknown to know. Since we are intelligent students, we will bring the unknowns to the left limb, and the numbers known in the right limb.
[tex]\:[/tex]
We can write this matematically as,
[tex]\rightarrow 167 = -x + 234[/tex]
Now we move the unknown to the left limb,
[tex]\rightarrow 167 + x = 234[/tex]
Now we move the term known to the right member,
[tex]\rightarrow x = 234 - 167[/tex]
We determine the value of x,
[tex]\rightarrow \underline { x = 67}[/tex]
