Penyelesaian dari 2(3x+5)-2 (7x-3)=x+7 adalah A.1 B.5 C.8 D.13

2(3x+5)-2(7x-3)= x+7
6x+10-14x+6=x+7
6x-14x+10+6=x+7
-8x+16=x+7
-8x-x=7-16
-9x=-9
x=-9/-9
x= 1
Jawabannya A

[tex]2(3x + 5) - 2(7x - 3) = x + 7[/tex]
[tex]6x + 10 - 14x + 6 = x + 7[/tex]
[tex] - 8x + 16 = x + 7[/tex]
[tex] - 9x = 7 - 16[/tex]
[tex] - 9x = - 9[/tex]
[tex]x = 1[/tex]
