Odpowiedź :

25+b=35
b=35-25
b=10


g+13=44
g=44-13
g=31


2x+14=x+24
x=24-14
x=10

3x+8=2x+17
x=17-8
x=8

Pozdrawiam ;*
25 + b = 35
b = 35 - 25
b = 10
-----------------
g +13 =44
g = 44 -13
g = 31
--------------
2x +14 = x + 24
2x - x = 24 - 14
x = 10
-------------------
3x +8 = 2x =17
3x -2x = 17 - 8
x = 9
25+b=35
b=35-25
b=10

g+13=55
g=44-13
g=31

2x+14=x+24
2x-x=24-14
x=10

3x+8=2x+17
3x-2x=17-8
x=9
