Va mutumesc ;D

Answer 1

a)(2+5)×A=707
2A+5A=707⇒7A=707⇒A=707/7⇒A=101
b)560/x=80⇒x=560/80⇒x=7
c)(40+6)×B=4600+56
40B+6B=4656⇒46B=4656⇒B=4656/46
d)x+263=1456-38
x+263=1418⇒x=1418-263⇒x=1155
e)15600/x=25⇒x=15600/25⇒x=624
f)85×A=85000⇒A=85000/85⇒A=100
g)3678-x+248+89⇒x=3678-337⇒x=3341
h)15430/x=60⇒x=15430/60
cred ca asta treb sa faci...
