Question

1) X-2461=5364-1681. 2) 2356+x=3537+269. 3) 6271-x=2347+257. 4) x-356=456+168.

Answer 1

Ответ:

1) х = 6144

2)х = 1450

3)х = 3667

4)х =  980

Пошаговое объяснение:

1) х = 5364-1681+2461

х = 6144

2) х = 3537+269-2356

х = 1450

3) х = 2347+257-6271

-х = -3667

х = 3667

4) х = 456+168+356

х = 980

Answer 2

Let's solve each of the equations step by step:

1. X-2461 = 5364 - 1681

To solve this equation, we'll simplify the right-hand side first:

5364 - 1681 = 3683

Now, we substitute this value back into the equation:

X - 2461 = 3683

To isolate X, we'll add 2461 to both sides of the equation:

X - 2461 + 2461 = 3683 + 2461

This simplifies to:

X = 6144

Therefore, the solution to the first equation is X = 6144.

2. 2356 + X = 3537 + 269

To solve this equation, we'll simplify the right-hand side first:

3537 + 269 = 3806

Now, we substitute this value back into the equation:

2356 + X = 3806

To isolate X, we'll subtract 2356 from both sides of the equation:

2356 + X - 2356 = 3806 - 2356

This simplifies to:

X = 1450

Therefore, the solution to the second equation is X = 1450.

3. 6271 - X = 2347 + 257

To solve this equation, we'll simplify the right-hand side first:

2347 + 257 = 2604

Now, we substitute this value back into the equation:

6271 - X = 2604

To isolate X, we'll subtract 6271 from both sides of the equation:

6271 - X - 6271 = 2604 - 6271

This simplifies to:

-X = -3667

To solve for X, we'll multiply both sides of the equation by -1:

(-1) * (-X) = (-1) * (-3667)

This gives us:

X = 3667

Therefore, the solution to the third equation is X = 3667.

4. X - 356 = 456 + 168

To solve this equation, we'll simplify the right-hand side first:

456 + 168 = 624

Now, we substitute this value back into the equation:

X - 356 = 624

To isolate X, we'll add 356 to both sides of the equation:

X - 356 + 356 = 624 + 356

This simplifies to:

X = 980

Therefore, the solution to the fourth equation is X = 980.

To summarize, the solutions to the given equations are:

1. X = 6144
2. X = 1450
3. X = 3667
4. X = 980
