Question

Hey ,va rog care poate sa faca doua din ecuatiile alea?!!!Dau coroana ,urgeenttt

Answer 1

a) (x-5)/2-(-2x+6)/3=-5(x+1)+7
3(x-5)-2(-2x+6)=-5*6(x+1)+7*6
3x-15+4x-12=-30x-30+42
7x-27=-30x+12
37x=39
x=39/37


b) -2(3x+1)/5 +3(-x+8)/4=3(x-1)+6
-2*4(3x+1) +3*5(-x+8)/4=3*20(x-1)+6*20
-24x-8-15x+120=60x-60+120
-39x+112=60x+60
21x=52
x=52/21
