Question

Solve the following equations:
2/3(6x+9)= -2(1/2x+4)

-3(2y-1)=4(1/2y+3/4)

Answer 1

2/3(6x+9)=-2 (1/2x+4)
2/3×6x=2/3×18/3=36/3×3=12/9
2/3×9=2/3×27/3=54/3×3=19/9
-2/1×1/2x=-4/2×1/2x=-4/2x
answer= 12/9x+18/9= -4/2x-8



-3 (2y-1)=4 (1/2y+3/4)
-3×2y=-6y
-3×-1= 3
4/1×1/2y 4/1×3/4
×2 ×4
8/2×1/2=8/2 16/4×3/4=48/4 ×4= 192/16×2=98/32×2=49/16
8/2×2=16/4×4=64/16×2=32/32=1
