Answer 1

c)

53 + 2x = x + 111

2x - x = 111 - 53

x = 58

d)

23 + 5x = 2x + 74

5x - 2x = 74 - 23

3x = 51

x = 51/3

x = 17

e)

32 + 6x = 11x - 113

32 + 113 = 11x - 6x

145 = 5x

x = 145/5

x = 29

f)

8 + 13x = 2x + 41

13x - 2x = 41 - 8

11x = 33

x = 33/11

x = 3

Sper că te-am ajutat!!

Answer 2

Explicație pas cu pas:

c)

$53 + 2x = x + 111 \\ 2x - x = 111 - 53 \\ x = 58$

d)

$23 + 5x = 2x + 74 \\ 5x - 2x = 74 - 23 \\ 3x = 51 \\ x = 51 : 3 \\ x = 17$

e)

$32 + 6x = 11x - 113 \\ 32 + 113 = 11x - 6x \\ 145 = 5x \\ x = 145 : 5 \\ x = 29$

f)

$8 + 13x = 2x + 41 \\ 13x - 2x = 41 - 8 \\ 11x = 33 \\ x = 33 : 11 \\ x = 3$
