Question

А*948-6390=429690 273996/b+15764=16151 (50-x)/7+195=40*5 (270/у-2)*30=7*120

Answer 1

А×948=429690+6390
а×948=436080
а=436080÷948
а=460

273996/b=16151-15764
273996/b=387
b=273996÷387
b=708

(50-x)/7=200-195
(50-x)/7=5
50-x=5×7
50-x=35
x=50-35
x=15

270/y-2=840÷30
270/y-2=28
270/y=28+2
270/y=30
y=270÷30
y=9
