Answer 1

4a*6a-2a+12-11=24a^2-2a+12-11=24a^2-2a+1

-8+5.2a+3x+5a=-8+10.2a+3x

5a+7a-9.2m+15m=12a-9.2m+15m=12a+5.8m

23x-23+40+4x=23x+17+4x=27x+17

-12z+3x+3.2z-2.3x=-8.8z+3x-2.3x=-8.8z+0.7x

Answer 2

4a*6a-2a+12-11 = 24a^2 - 2a + 1

-8+5.2a+3x+5a = 7.2a + 3x - 8

5a+7a-9.2m+15m = 12a + 6m - 9

23x-23+40+4x = 27x + 17

-12z+3x+3.2z-2.3x = -12z + 3x + 3.2z - 2.3x = 0.9z - 0.3x - 12
