Answer:
3?
Step-by-step explanation:
Answer:
The three natural numbers whose sum and product are equal are 1, 2 and 3.
By eg.,1+2+3=6 &1×2×3=6.
From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:
-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12
Hope this helps. Have a nice day.

X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
