2x 3x - 1


tolong jawabkan yah...

Answer 1

1.) 2(x + 4) = -3(x-4) → 2x+8=-3x+12→2x+3x=12-8→5x=4→x=4\5=0,8
2.) 2x - 5 = 7 + 5→2x=12+5→2x=17→x=17\2=8,5
3.) 10x + 2 = 7 + 5x→10x-5x=7-2→5x=5→x=5\5=1
4.) 8 = 2x + 5→8-5=2x→3=2x→x=2\3
5. )40 = 5 + 5x→40-5=5x→35=5x→x=35\5=7
6. )3x = x + 4→3x-x=4→2x=4→x=4\2=2

7. ) 3x + 5 = 2x - 4→3x-2x=-4-5→x=-9

2 4
8. ) 4 2
