Answer 1

Răspuns:

Păi este destul de simplu.

Explicație pas cu pas:

a) 1753- x =783

=> x = 1753-783

=> x= 980

b) x- 633 =2941

=>x = 2941 - 633

=>x = 2308

Answer 2

20. a) x+89=115

x=115-89

x=26

b) 2×x+23=91

2×x=91-23

2×x=68

x=68:2

x=34

c) 327-3×x=15+48

327-3×x=63

3×x=327-63

3×x=264

x=264:3

x=88

d) 15+(x+2)+21=47

x+17+21=47

x+38=47

x=48-37

x=11

e) 2×x+37=79-14

2×x+37=65

2×x=65-37

2×x=28

x=28:2

x=14

f) 32+(2×x-5)=63+14

2×x+27=77

2×x=77-27

2×x=50

x=50:2

x=25
