1. Jawaban arsul1909
1. 1/6 × ( X/2 + 3/4 ) = X/2 + 1/3 =
=1/6 x (x/2-x/2)+3/4-1/3
=2+9-4/12
=7/12
2. 2/3 × ( X/8 - 3/4 ) = X/2 - 1/2 =
=2/3 x (x/8-x/2)-3/4+1/2
=8-9-6/12
=-7/12
3. X - 2 /2 + X - 4/3 = 1/6
=x+x-2/2-4/3-1/6
=2x-6-8-1/6
=2x-15/6
4. X + 1/3 - X -4 = 5/12X
=x-x4-12/12-5/12x
=-8/12-5/12x
5. 1/2 × ( X - 1 ) - 1/3 × ( X + 3 ) = 1/6
=3-2-1/6 (X+X-1+3)
=2X+2
6. 1/3 × ( X - 2 ) - 1/4 × ( X - 5 ) = X/66.
=4-3/12(2X-7)-X/66
=1/12 (2X-7) - X/66
7. X + 2/3 - 3X -1 = X/9
=X-3X-1+2/3-X/9
=-2X-1+2/3-X/9
8. X + 3/4 - 2X - 5/5 = 7/10
=X-2X+15-20-14/20
=-X19/20
9. 1/4 × ( X - 3 ) + 1/6 × ( 2X - 3 ) = 4
=3+2/12(X+2X-3-3)-4
=5/12(3X-6)-4
=5/12(3X-10)
10.1/2 ( X + 1/3 ) + 1/4 × ( 2/3X - 1/6 )= X
=2+1/4(X-X+2/3X+1/3-1/6)
=3/4(2/3X+1/6)
maaf kalau salah
