Question

Ajutor urgent vă rog frumos. Ex 3.

Answer 1

Răspuns:

3. a) 7 864 + m = 9 503

m = 9 503 - 7 864

m = 1 639

n - 587 = 4 839

n = 4 869 + 587

n = 5 426

b) 8652 - a + 240 = 2345

8652 - a = 2345 - 240

8652 - a = 2105

a = 8652 - 2105

a = 6547

Answer 2

Răspuns:

Salut

a)7864+m=9503

m=9503-7864

m=1639.

b)n-587=4839

n=4839+587

n=5426.

c)8620-r=5873

r=8620-5873

r=2747.

b)8652-a+240=2345

8865-a=2345

a=8865-2345

a=6520.
