Answer:
{x:x<3}
Step-by-step explanation:
You first change the < to = in order to simply it. Thus,
- 2x-5=1
- 2x=1+5( move the -5 to the right hand side to obtain 5)
- 2x= 6
- dividing through by 2
- 2x/2=6/2
x=3 . Therefore the solution is {x:x<3} <u>sing you didn't divide with a</u> <u>negative number ,the < sing remains unchanged</u>
<h3>
</h3>
Substituting the value of x in
( equation 2)
Now we get y = 6
Substituting the value of y in
( equation 1 )
Now we get x = 3
<h3>y = 6 </h3>
<h3>x = 3</h3>
Answer:
y = 2/x
Step-by-step explanation:
You cannot divide by zero because you will get an undefined value, and this will create a hole in the graph.
It has one solution Bc there is only one variable
