21
It is: -17+38 = 21
-15 + x = 21Add 15 to each side of the equation:x = 36
The result is: -4-20 = -24
157
It is 40 because -19+40 = 21
15

It is 31.
It is: -17+38 = 21
If the largest integer is subtracted from four times the smallest, the result is 4 more than twice the middle integer. Let the smallest integer be x, then the others are x + 2 and x+ 4. Therefore 4x - (x + 4) = 2 (x + 2 ) + 4 Expanding, we get 4x -x -4 = 2x + 4 + 4 Gathering terms: x = 12 Thus the three integers are 12, 14 and 16.
-15 + x = 21Add 15 to each side of the equation:x = 36
The result is: -4-20 = -24
141+20=161, 161/7=23. The answer is 23. It is algebra
Let the number be x:- If: 7x -22 = 125 Then: x = 21
When a positive number is subtracted from zero the result is a negative number.
