Question

a)26+x*3=50
b)480:y-19=41
c)160/t+18=25*2
d)k/7-34=78:3
e)9*9-540:(a-27)=15*5
f)80*b-3*90+430=1600:2
g)6 1/7-(c+2 4/7)=2 5/7

Answer 1

х*3=50-26
х*3=24
х=24:3
х=8

480:у=41+19
480:у=60
у=480:60
у=8

160/t=25*2-18
160/t=32
t=160:32
t=5

k/7=78:3+34
k/7=60
k=60*7
k=420

-540:(а-27)=15*5-81
-540:(а-27)=-6
а-27=540:6
а-27=90
а=90+27
а=117

80*б=1600:2+270-430
80б=640
б=640:80
б=8
