Answer 1

-0.4y +5=37

-0.4y=37-5

-0.4y=32

y=32/(-0.4)

y=-80

$14-x=\frac{1}{4}x -1\\4(14-x)=4(\frac{1}{4}x-1)\\4*14-4x=4*\frac{1}{4}x-4\\56-4x=x-4\\-4x-x=-4-56\\-5x=-60\\x=12$

$x-\frac{1}{2}x-\frac{1}{5}x=12\\10(x-\frac{1}{2}x-\frac{1}{5}x)=10*12\\10x-10x*\frac{1}{2}x-10*\frac{1}{5}x=120\\10x-5x-2x=120\\3x=120\\x=40$

$\frac{6p}{17} -\frac{p}{3} =1\\51(\frac{6p}{17} -\frac{p}{3})=51*1\\51*\frac{6p}{17} -51*\frac{p}{3}=51\\3*6p-17p=51\\18p-17p=51\\p=51$

1.8x-(x-4.3)=(0.2x+0.5)-1.6

1.8x-x+4.3=0.2x+0.5-1.6

0.8x+4.3=0.2x-1.1

0.8x-0.2x=-1.1-4.3

0.6x=-5.4

x=-9

24=6(x-5)

24/6=6(x-5)/6

4=x-5

-x=-5-4

-x=-9

x=9
