Question

Gaseste valorile necunoscute m,n,p,r. 136×12-3×m=1 605. 36:p+324×22=7 137. 279×25+n×5=7 010 64:r+530×18=9 548.

Answer 1

136x12-3xm=1605
1632-3xm=1605
3xm=1632-1605
3xm=27
m=27:3
m=9

36:p+324x22=7137
36:p+7128=7137
36:p=7137-7128
36:p=9
p=36:9
p=4

279x25+nx5=7010
6975+nx5=7010
nx5=7010-6975
nx5=35
n=35:5
n=7

64:r+530x18=9548
64:r+9540=9548
64:r=9548-9540
64:r=8
r=64:8
r=8

Mult succes la școală!
