Tolong bantu yaa makasih

Answer 1

1. 7x/2 = 1-x/6
7x/2 = 6 - x / 6
2(6-x) = 6 (7x)
12-2x = 42x
12 = 42x + 2x
12 = 44x
x = 12/44
x = 3/11

2. r-2/3 + 4 < -2 r+4/4
r-2/3 + 4 < -r+4/2
r-2/3 + r+4/2 < -4
2(r-2)/6 + 3(r+4)/6 < -4
2r - 4 /6 + 3r + 12 / 6 < -4
5r + 8 per 6 < -4
_____________ kalikan dengan 6
5r + 8 < -24
5r < -24-8
5r < -32
r < -32/5
