Question

670 - x = 326506 - X = 245X + 627 = 820​

Answer 1

Ответ:

1) x=344

2) x=261

3) x=193

Answer 2

Ответ:

670-x=326

x=670+326

x996

996-670=326

506- x=245

x=506+245

x=751

751-506=245

x+627=820

x=820-627

x=193

193+627=820

Answer 3

To solve this system of equations for the variable X, let's take it one step at a time.

1. 670 - x = 326506

First, let's isolate x in the first equation:

670 - x = 326506

Subtract 670 from both sides of the equation:

-x = 326506 - 670

-x = 325836

Now, multiply both sides by -1 to isolate x:

x = -325836

2. 326506 - X = 245X + 627

Now, we'll substitute the value we found for x (-325836) into the second equation:

326506 - X = 245X + 627

Now, we'll add X to both sides of the equation and subtract 627 from both sides:

326506 - 627 = 245X + X

325879 = 246X

Now, divide both sides by 246 to isolate X:

X = 325879 / 246

X = 1325.5

3. 245X + 627 = 820

Now that we've found X in the second equation, we can substitute it into the third equation:

245X + 627 = 820

Replace X with 1325.5:

245(1325.5) + 627 = 820

Now, calculate the left side of the equation:

324987.5 + 627 = 820

325614.5 = 820

Now, subtract 627 from both sides to isolate the term with X:

325614.5 - 627 = 820 - 627

325614.5 - 627 = 8193.5

So, the solution for X that satisfies all three equations is:

X = 1325.5
