Question

X(+54)-28=69, (x+120)•2=320

Answer 1

Ответ:

1) Х = 1,8. 2) Х = 40

Пошаговое объяснение:

х(+54) - 28 =69

54х - 28 = 69

54х = 69 + 28

54х = 97

х = 97 ÷ 54

х = 1,8

(х+120)*2 = 320

240 + 2х = 320

2х = 320 - 240

2х =80

х =80 ÷2

х = 40

Answer 2

To solve these equations, let's work on each one separately:

1. X + 54 - 28 = 69

First, combine like terms:

X + 26 = 69

Now, isolate X by subtracting 26 from both sides of the equation:

X = 69 - 26 X = 43

So, the solution to the first equation is X = 43.

2. (X + 120) * 2 = 320

First, distribute the 2 on the left side of the equation:

2(X + 120) = 320

Now, divide both sides by 2 to isolate X:

(X + 120) = 320 / 2 (X + 120) = 160

Now, subtract 120 from both sides to find X:

X = 160 - 120 X = 40

So, the solution to the second equation is X = 40.
