Question

afla numarul necunoscut. 9180 -m=659 p×8=56 n-489=7741 q:7=10

Answer 1

9180- m=659
9180-659= m
m=8521
p×8=56
p=56:8=7
n-489=7741
n=7741+489
n=8230
q:7=10
q=7×10=70

Answer 2

9180 - m = 659

- m = 659 - 9180

- m = - 8521

m = 8521

V : 9180 - 8521 = 659

-------------------------------------

p x 8 = 56

8p = 56

p = 56 : 8

p = 7

V : 7 x 8 = 56

---------------------------------

n - 489 = 7741

n = 7741 + 489

n = 8230

V : 8230 - 489 = 7741

----------------------------------

q : 7 = 10

q = 10 x 7

q = 70

V : 70 : 7 = 10
