Question

1) x+306=556 2) 700*2-308=... 3)1000-x+300*2=1595

Answer 1

Ответ:

х+306=556

х=556-306

х=250

700×2=1400-308=1092

1000-x+300*2=1595

1000-х+600=1595

1000-х=1595-600

1000-х=995

х=5

Answer 2

Let's solve these equations one by one:

1. x + 306 = 556

To solve for x, you need to isolate x on one side of the equation. You can do this by subtracting 306 from both sides of the equation:

x + 306 - 306 = 556 - 306

x = 250

So, the solution for this equation is x = 250.

2. 700 * 2 - 308 = ...

To solve this equation, you simply perform the arithmetic operations:

700 * 2 - 308 = 1400 - 308 = 1092

So, the solution for this equation is 1092.

3. 1000 - x + 300 * 2 = 1595

First, let's simplify the equation:

1000 - x + 600 = 1595

Now, let's isolate x by moving the constants to the other side of the equation:

1000 + 600 - 1595 = x

1600 - 1595 = x

5 = x

So, the solution for this equation is x = 5.
