Verified answer

1) 4/9x+14=1/6x+9

 8x+258=3x+162

 8x-3x=162-252

 5x=-90

 x=-18

2) 0.3(6-3)=4.5-0.8(y-9)

 1.8-0.9y=4.5-0.8y+7.2

 1.8-0.9y=11.7-0.8y

 -0.9y+0.8y=11.7-1,8

 -0.1y=9.9

 y=-99

1. x+4=96x

-95x=-4

x=4

95

2. 1, 8 + 0, 9y = 4, 5 + 0, 8y + 7, 2

0, 9y + 0, 8y = 4, 5 + 7, 2 - 1, 8

0, 1y = 9, 9

y = 9, 9 / (0, 1)

y = - 99
