To na jutro.. pomocy !!!

Rozwiąż równania i sprawdź.

a. 2(x-3)-(3x-1)= 5
b. 3(x-2)+2(4-x)= 6
c. (x+3)-(2x-1)= 1
d. -(x=1)-2(1-x)= 4
e. -2 (1-x)=3(2x=1)= -7
f. -3 (2-x) -2(1-3x) =10
g. 2(x+3)-(5-x)+2= 3-(x-1)
h. 3(x-4)-2(3-2x) = -(3x-1)-(1-x)
i. 2x- (x+4)- 1 = 2-3(1-x)+3
j. 1-2(x-3)-(3x+5) = -x-(2x-1)+3
k. (x+2+(x-3)-(4-x) = -(2x-5)-(3-x)+ (2x-4)
l. 2(1-x)=3(x+1)-(x-3) = (2x+
3)-(4-x)-2(3-2x)
m. 0,2x - 0,5 = 2,1
n. 2,1x - 1,4 = 1,7x+ o,2
o. 0,3x+o,4= -o,2
PS. jestem w 1klasie gim. proszę o w miare proste odp.
