Question

2) x + 2387 = 4005;4) 13 892 + x = 79 159.​

Answer 1

2)

x + 2387 = 4005

х = 4005 - 2387

х = 1618

-------------------

1618 + 2387 = 4005

4005 = 4005

4)

13892 + x = 79159

х = 79159 - 13892

х = 65267

-------------------

13892 + 65267 = 79159

79159 = 79159

Answer 2

2) х + 2387 = 4005
х= 4005-2387
х=1618
4) 13 892 + х = 79 159
х= 79159-13892
х=60267

Answer 3

To solve these equations for x, you need to isolate x on one side of the equation. Here's how you can do it for each equation:

1. x + 2387 = 4005

First, subtract 2387 from both sides of the equation to isolate x:

x + 2387 - 2387 = 4005 - 2387

x = 1618

So, the solution for x in this equation is x = 1618.

2. 13,892 + x = 79,159

First, subtract 13,892 from both sides of the equation to isolate x:

13,892 + x - 13,892 = 79,159 - 13,892

x = 65,267

So, the solution for x in this equation is x = 65,267.
