Distribute

(3/4)(4c)+(3/4)(16)=2c/9

3c+12=2/9 c

Now subtract 2/9 c from both sides

3c+12-2/9 c=2/9 c-2/9 c

25/9 c+12 =0

Now we need to subtract 12 from both sides

25/9 c+12-12=0-12

25/9 c=-12

Just multiply both sides by 9/25 so we find the value for c

25/9 *(25/9 c)=-12(9/25)

c= -108/25

I hope that's help:0
