Question

17 x-3,2x=62,1 34,5÷x-12,5=1,3

Answer 1

Ответ:

4,5 і 2,5

Пошаговое объяснение:

1)17 x-3,2x=62,1

13,8х=62.1

Х=4,5

2) 34,5÷x-12,5=1,3

69/2÷х-12,5=1,3

69/2х-25/2=1,3

69/2х=1,3+25/2

69/2х=69/5

2х=5

х=5/2 або 2,5

Answer 2

Ответ:

1 пример

$17x - 3.2x = 62.1$

$x = 4.5$

2 пример

$34.5 \div x - 12.5 = 1.3$

$x = 2.5$

Answer 3

To solve the equations, let's start with the first one:

17x - 3(2x) = 62.1

Simplifying the equation:

17x - 6x = 62.1

11x = 62.1

Dividing both sides by 11 to isolate x:

x = 62.1 / 11

x ≈ 5.64

Now, let's move on to the second equation:

34.5 ÷ x - 12.5 = 1.3

To eliminate the fraction, we can multiply both sides of the equation by x:

34.5 - 12.5x = 1.3x

Combining like terms:

34.5 = 1.3x + 12.5x

34.5 = 13.8x

Dividing both sides by 13.8 to isolate x:

x = 34.5 / 13.8

x ≈ 2.50

Therefore, the solutions to the given equations are approximately x = 5.64 and x = 2.50.
