Answer 1

51.

3X - 5 = 2X + 3

X = 8

52.

X/3 + 12 = 26

X = 42

53.

Y = X - 43

X + Y =365

X + X - 43 =365

2X = 408

X = 204

54.

X + (X - 1) + (X - 2) = 69

3X - 3 = 69

3(X - 1) = 69

X = 23 + 1 = 24

24/2 = 12

55.

(1 - 1/4 - 1/3)X = 75pag

(5/12)X = 75pag

X = 180pag

56.

X + 2(X + 1) = 74

3X + 2 = 74

X = 24

58.

3X - 11 = 43

X = 18

59.

(1 - 1/2 - 1/4)X = €3

(1/4)X = €3

X = €12

60.

( 1 + 1/2 + 1/4)X + €1 = €64

(7/4)X = €63

X = €36
