Answer 1

 zad 23 6x+15x=21x    -12a-20a=8a     -5t-(-4t)-7t=-8t    -2x+6x=4x    -3c=2c-20c=-21c   -k-k-(-k)+(-8k)=-9k    -8x+3x=-5x     -(-3m)-2m+(-4)=-3m

 

zad24 2x+y-x+4y=3x+5y      3x-2+14x=17x-2     8x-4-15x-7=-7x+(-11)    -5x+3y-6x-13y=x-10y     0,5x+2,1y+3,7x-0,2y=4,2x+1,9y              1/3x-y-y-2/3x=-1/3x-2y
