Question

Tolong bnatu saya ini dikumpul bsok pliease
1. 2-z= z – 3
2. 18= 10 – 2m
3. 2(3x-1) = 2 (2x+3)
4. 1/2 (4x+2) = 3
5. 8 - 2 (3-4y) = 7y -1
6. 7x = 8 + 3x
7. K – 9 =13
8. -2x + 5 = -(x+9)
9. 5(y-1) = 4y
10. 3(2x-3) –2 (1-x) – (x+3) = 0

Answer 1

1. 2-z=z-3 2+3=z+z 2=5z z=5/2=2,5 2.18=10-2m 18-10=-2m 8=-2m M=-4 3. 2(3x-1)=2(2x+3) 6x-2=4x+6 6x-4x=6+2 2x=8 X=4 4. 1/2(4x+2)=3 2x+1=3 2x=2 x=1 5. 8-2(3-4y)=7y-1 8-6+8y=7y-1 8-6+1=7y-8y 3=-y Y=-3 Yang 5 mungkin djwb tmn lain,smoga bisa bntu,soale ini ada acara,trims 6. x=2 7. K=22 8. X=14 9. Y=5 10. X=2
