Question

Daca imi rezolvati toate cele 3 exerciti primiti coroana + cele 100 de puncte!

Answer 1

4) a) 2x-3=x+1 => x=4  
b) 4-3x=x+3 => -1/-4 = 1/4 
c) 5x-1=-2x+6 => x=7/7 = 1
d) 4(x-2) = 3x+7 => x=15 
e) 5x-2=3(x+4) => x=14/2 = 7
f) 2(x+3) = 3(x+2) => x=0 
g) 5(2x-1)=3(3x+2) => x=11 
h) 2(1-2x)=3(2-x)=> x= -4
