Let the number be x,y and 43
y-x=10
thus
y=10+x
the sum off the numbers will be:
x+y+43=79
plugging the values we get:
x+(10+x)+43=79
solving for x we get:
2x+53=79
2x=79-53
2x=26
x=26/2=13
hence:
y=10+13=23
thus the numbers are 13,23 and 43
the product of the number will be:
13×23×43
=12,857

Answer: 12,857

<h3>Look at the picture.</h3>

<em>commutative property</em>  a + b = b + a

... (-5 + 1/2 + 5) = ... (-5 + 5 + 1/2)

<em>inverse property of addition</em> a + (-a) = a - a = 0

... (-5 + 5 + 1/2) = ... (0 + 1/2)

<em>identity property of addition</em> a + 0 = 0 + a = a

... (0 + 1/2) = ... 1/2

<em>inverse property of multiplication</em> a/b · b/a = 1

37 · 2 · 1/2 = 37 · 2/1 · 1/2 = 37 · 1

<em>identity property of multiplication</em> a · 1 = 1 · a = a

37 · 1 = 37

If we are eliminating x, we would multiply the 2nd equation by -5

5x + 18y = 23
x + 3y = 2....multiply by -5
-----------------
5x + 18y = 23
-5x - 15y = - 10 (result of multiplying by -5)
----------------add
0 + 3y = 13.....bye-bye x :)
