Question

completa los espacios con equis (X) de tal manera que se cumplan las equivalencias

x . 3 = 144
4+(5 . x)= 144
(x - 1). 2²= 144
(7 . 15) + x = 144
(2 . x)²= 144
6 . (x - 2)= 144

Answer 1

x . 3 = 144

X = 144/3

X = 48
>>>>>>>>>

4+(5 . x)= 144
5.x = 144-4
X = 140/5
X = 28
>>>>>>>>>
(x - 1). 2²= 144
(x-1).4 = 144
4x -4 = 144
4x = 144+4
X = 148/4
X = 37
>>>>>>>>>
(7 . 15) + x = 144
X = 144 -105
X = 39
>>>>>>>>>
(2 . x)²= 144
2x = ±√144
2x = ±12
x = ±12/2

X¹ = 6
X² = -6
>>>>>>>>>
6 . (x - 2)= 144
6x -12 = 144
6x = 144 +12
X = 156/6
X= 26
