8x^2-5x-2
method
open bracket
6x^2-2x-3+x^2-3x+1
collect like terms
6x^2+2x^2-3-3x+1
8x^2-3-3x+1
again collect like terms
8x^2-2x-3x-3+1
8x^2-5x-3+1. (-×-=+ addition but keeping sign minus
8x-5x-2. (-×+=-)
6.31 is a rational number.
3x + 2y = 3. subtract 3x from both sides, so you get 2y = -3x + 3 . then you divide by 2 to both sides , so you get y = -3/2x + 3/2 .
