Answer:
c=7
Step-by-step explanation:
The problem says that 8 less than 4 times c is less than twenty, so we can first show 8 less than 20.
4c -( I did this because it said 4 times the number c)
Then, we show 8 less than that.
4c-8
It says it is twenty, and that means it equals twenty.
4c-8=20
Now we solve!
4c-8=20
+8 +8
*we add 8 to both sides*
4c=28
*we divide both sides by 4 since we want to isolate c*
c=28/4
c=7
I hope this helped!
Answer: The numbers are 1 and 3.
Step-by-step explanation:
Let x = smaller number , y= larger number.
As per given,
...(i)
...(ii)
Put value of x from (i) in (ii)
Since numbers are positive , so y=3 is correct.
And x will be 1 [from (i)]
Hence, the numbers are 1 and 3.

Answer:
(-1,3)
Step-by-step explanation:
so y=x+4 and y=-2x+1
obviously, y=y
so that means that x+4 is equal to -2x+1
let's use that
y=x+4,y=-2x+1
y=y
x+4=-2x+1
x+2x=1-4
3x=-3
x=-1
y=x+4
y=(-1)+4
y=3
(-1,3)
