Tentukan himpunan penyelesaian:
a. 2(5 - 24)=3(5 - x)
b.-2x + 5= -(x + 9)
c.18 + 7x =2(3x - 4)
d.3(2x -3) - 2x -x) - (x + 3)=0
a. 2(5 - 24)=3(5 - x)
b.-2x + 5= -(x + 9)
c.18 + 7x =2(3x - 4)
d.3(2x -3) - 2x -x) - (x + 3)=0
10-48=15-3x
-38=15-3x
-38+15=3x
-23=3x
x=-23/3
b.-2x+5=-(x+9)
-2x+5=-x-9
-2x+x=-9-5
-x=-14
x=14
c.18+7x=2(3x-4)
18+7x=6x-8
7x-6x=-8-18
x=-26
d.soalnya tolong di tulis lagi
