600-252=348;100-56=44

Answer 3

To solve these equations, let's go through them one by one:

1. Х-78=18

To find the value of Х, we need to isolate it on one side of the equation. To do that, we can add 78 to both sides of the equation:

Х - 78 + 78 = 18 + 78 Х = 96

So, Х = 96.

2. 18 600 - х = 252

To find the value of х, we'll need to isolate it on one side of the equation. To do that, we can subtract 252 from both sides of the equation:

18 600 - х - 252 = 252 - 252 18 600 - х = 18 348

Now, to get х alone, we can subtract х from both sides:

18 600 - х - х = 18 348 - х 18 600 - 2х = 18 348

Next, we can isolate х by dividing both sides by 2:

(18 600 - 2х) / 2 = 18 348 / 2 9 300 - х = 9 174

Finally, let's isolate х on one side:

-х = 9 174 - 9 300 -х = -126

Now, to find the value of х, we can multiply both sides by -1:

х = 126

So, х = 126.

3. х + 56 = 100

To find the value of х, we'll need to isolate it on one side of the equation. To do that, we can subtract 56 from both sides of the equation:

х + 56 - 56 = 100 - 56 х = 44

So, х = 44.

In summary, the solutions to the equations are: Х = 96 х = 126 х = 44
