How do I find the additive inverse of something in Algebra??For example, my book says to find the additive inverse of:1. a+b+c2. 8x-6y+133. -2c+5d-3e+4fI don't understand what they're asking me to do.
Must sum to zero hence answers are 1 - ( a + b + c ) 2 - ( 8x - 6y + 13) 3 - (-2c + 5d - 3e + 4f)
The additive inverse of a number is some number that when added to the original equals zero. The additive inverse of 2 is negative 2 ... 2 + (-2) = 0 The additive inverse of x is - x ... x + (-x) = 0 a + b + c . . . additive inverse = - a - b - c Yes, it really is that simple. 8x - 6y + 13 ===> - 8x + 6y - 13 - 2c + 5d - 3e + 4f ===> 2c - 5d + 3e - 4f
