Question

228+200:х=230 Х*9=720-90

Answer 1

1)
$228 + 200 \div x = 230$
$200 \div x = 230 - 228$
$x = \frac{200}{2}$
$x = 100$

2)
$x \times 9 = 720 - 90$
$x \times 9 = 630$
$x = \frac{630}{9}$
$x = 70$

Answer 2

Ответ:

1      х = 100

2     х =70

Пошаговое объяснение:

228+200/100=230

70*9=720-90

Answer 3

To solve the equations, let's break it down step by step:

1. The first equation is: 228 + 200 / x = 230.

To isolate x, we need to move 228 to the right side of the equation by subtracting it from both sides:

228 + 200 / x - 228 = 230 - 228.

This simplifies to:

200 / x = 2.

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

x * (200 / x) = 2 * x.

The x on the left side cancels out, leaving us with:

200 = 2x.

Divide both sides by 2 to solve for x:

200 / 2 = 2x / 2.

100 = x.

Therefore, x = 100.

2. The second equation is: x * 9 = 720 - 90.

We can solve this equation by simplifying each side:

9x = 720 - 90.

Combine like terms:

9x = 630.

To solve for x, divide both sides by 9:

9x / 9 = 630 / 9.

x = 70.

Therefore, x = 70.

In summary, the solution to the system of equations is x = 100 and x = 70.
