Question

y*(17*3)=204
d+(71-52)=138
c-14*3=68
c/(116/2)=4
200-x/6=180   

Answer 1

$1)y*(17*3)=204 \ 51y=204\y= frac{204}{51} \ y=4 \ \ 2)d+(71-52)=138 \ d+19=138\d=138-19 \ d=119 \ \ 3)c-14*3=68 \ c-42=68\c=68+42\c=110$

$4) c:(116:2)=4 \ frac{c}{58} =4 \ c=58*4 \ c=232 \ \ 5)200- frac{x}{6} =180 \ frac{x}{6} =200-180 \ frac{x}{6} =20 \x=20*6 \ x=120 \ x=120$
