Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)
(2) x 2 => 2x + 6y = 112 . . . (3)
(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17
The two numbers are 13 and 17.
The answer is 72 and 73. When you add 72+73 it equals 145.
Answer:

Step-by-step explanation:
Given

Required
Express as a standard polynomial
We have:

Rewrite as:

Open bracket

Add like terms

15x+3x+10 = 38x-20x+10
18x+10 = 18x+10
18x-18x = 10-10
0 = 0
The equation is true.
