Answer 1

a)(159-154)x m=715
5m=715
m=143
b)808-a=209
a=599
c)777-a=478
a=299
d)919-a=1313
a=349
e)a+270=500
a=230
f)36\a+7=16*inmultim cu 36
a+252=576
a=320

Answer 2

(795:5-154)xm=715
(159-154)xm=715
5xm=715
m=715:5
m=143

(808-a)x2=418
(808-a)=418:2
808-a=209
a=808-209
a=599

(777-a)-258=220
777-a=220+258
777-a=478
a=777-478
a=299

(919-a)+687=2000
919-a=2000-687
919-a=1313
a=1313-919
a=394

a+30x9=500
a+270=500
a=500-270
a=230

(36:a+63:9):2=8
(36:a+7)=8x2
(36:a+7)=16
36:a=16-7
36:a=9
a=36:9
a=4
