URGENTTTTTTTTTTTT!!!!!!!!!!!!!!!!!!!!!!!
VA ROG!!!!!!!!!!

Answer 1

a)2x-3,14+x=x+12
2x=12+3,14
2x=15,14
x=7,57

c)3x-12,25+2x+x=x-6,25
5x=-6,25+12,25
5x=6
x=6/5=1,2

b)4x-2,15+3x=+7,85
 4x=+7,85+2,15
4x=10
x=10/4=5/2=2,5

d)8x+1,345-2x=7,395-2x+0,35
8x=7,395+0,35-1,345
8x=6,4
x=0,8

e)14x+12,25-7x=24,01-7x
14x=24,01-12,25
14x=11,76
x=0,84
