Question

0.75*(0.5x+2/3)=3x+2 1/4

Answer 1

$0.75*(0.5x+ frac{2}{3} )=3x+2 frac{1}{4} \ \ 0.5x+ frac{2}{3}=(3x+2.25):0.75 \ \ 0.5x+ frac{2}{3}=4x+3 \ \ 0.5x-4x=3- frac{2}{3} \ \ -3.5x= 2 frac{1}{3} \ \ 3 frac{1}{2}x=- 2 frac{1}{3} \ \ x=- 2 frac{1}{3}: 3 frac{1}{2}$

$x=- frac{7}{3}* frac{2}{7} \ \ x=- frac{2}{3}$
