use algebra and then factor... x= -9 and 9
1+9+25=35 not 41, this is a false statement
Simple algebra, 2a-20 = -2 2a=18 a=18/2 a=9
When you subtract a negative number, that is the same thing as adding a positive number, so this equals 10.
For example 5x \ 9 x 5 + 10 + 72 = 9 So you move 72 over to 9 and minus it 5x / 9 x 5 + 10 = 9-72 Then bring 10 over 5x / 9 x 5 = -63- 10 Then brong 5 over 5x / 9 equals - 73 5x equals -73 times 9 5x equals 146 X equals to 146 divide by 5 Thanks you Hello Israel
