5x -30= 2x-6
3x= 24
x= 8
maka x+3= 8+3=11
no.2
persamaan diatas dikali 12 biar gak ribet
3(x-10)=8x-60
3x-30=8x-60
-5x=-30
x=6
= 5x-2x=-6+30
=3x=24
maka x=8 lalu x+3=8+3=11
2. 1/4x - 10/4 = 2/3x-5
= 1/4x - 2/3x = -5 +10/4
= 3/12x - 8/12x = -20/4 + 10/4
= -5/12x = -10/4
= -20x = -120
= x= -120/-20
=6
