Diketahui 2 per 3 (6x - 9) = 1 per 2 (4x + 8). Nilai x + 10 =....

2/3(6x - 9 ) = 1/2(4x +8)
4x - 6 = 2x + 4
4x - 2x = 4 +6
2x = 10
x = 10/2 = 5
x + 10 = 5 + 10 = 15

2/(18x-27) = 1/(8x+16)
kalikan silang
2(8x+16) = 1(18x-27)
16x+32 = 18x-27
16x-18x = -27 - 32
-2x = -59
x=-59/-2
x= 29,5

jadi, nilai x+10=29,5+10=39,5

maaf kalau ada kesalahan
