Question

(64+123+239)*f=1278

(394-123-g):2=108
(44 ori 5:10+h=331

Answer 1

(64+123+239)*f=1278
(187+239)*f=1278
426*f=1278
f=1278:426
f=3

(394-123-g):2=108
271-g=108x2
271-g=216
g=271-216
g=55

(44*5:10+h)=331
220:10+h=331
22+h=331
h=331-22
h=309

Answer 2

426*f=1278⇒f=1278:426⇒f=3
271-g=108*2⇒271-216=g⇒g=55
220:10+h=331⇒22+h=331⇒h=309
