Answer 2

To solve the equations, let's go step by step:

1. 228 + 200:х = 230
2. Х•9 = 630

Step 1: To solve the first equation, we need to isolate 'х' on one side of the equation.

First, subtract 228 from both sides of the equation: 228 + 200 - 228 = 230 - 228

This simplifies to: 200:х = 2

Now, to solve for 'х', we need to get rid of the division symbol (':'). Since division is the inverse operation of multiplication, we can multiply both sides of the equation by 'х':

200:х * х = 2 * х

The 'х' on the left side cancels out, leaving us with: 200 = 2 * х

Finally, divide both sides by 2 to solve for 'х':

х = 200 / 2 х = 100

So, the value of 'х' is 100.

Step 2: Now that we have the value of 'х', let's solve the second equation:

Х•9 = 630

Substitute the value of 'х' (which is 100) into the equation:

100 • 9 = 630

Now, simply calculate the product:

900 = 630

This equation is not true since 900 is not equal to 630.

Therefore, the solution is not valid for the second equation. Please double-check the second equation or the value of 'х'. If you have made any errors while typing, feel free to correct them, and I'll be happy to assist further.
