Answer 1

1) 39+х = 78+84, 39+х=162, х=162-39=123.

2)х-83 =425-316, х-83=109, х=109+83=192.

3)600-х = 126+92, 600-х=218, х = 600-218=382.

4) х-459 = 253-138, х-459=115, х=115+459=574.

5)217-х=502-421, 217-х = 81, х = 217-81=136.

6)х+157 = 871-385, х+157=486, х = 486-157=329.

Answer 2

Solving the Equations:

Let's solve the given equations step by step:

1) 39 + x - 84 = 782

To solve this equation, we need to isolate the variable x. We can do this by performing inverse operations. First, let's add 84 to both sides of the equation:

39 + x - 84 + 84 = 782 + 84

Simplifying the equation:

x = 866

Therefore, the solution to the first equation is x = 866.

2) x - 83 + 316 = 425

To solve this equation, we need to isolate the variable x. Let's start by adding 83 and 316:

x - 83 + 316 + 83 = 425 + 83

Simplifying the equation:

x + 233 = 508

Next, let's isolate x by subtracting 233 from both sides:

x + 233 - 233 = 508 - 233

Simplifying the equation:

x = 275

Therefore, the solution to the second equation is x = 275.

3) 600 - x - 92 = 126

To solve this equation, we need to isolate the variable x. Let's start by subtracting 92 from both sides:

600 - x - 92 + 92 = 126 + 92

Simplifying the equation:

600 - x = 218

Next, let's isolate x by subtracting 600 from both sides:

600 - x - 600 = 218 - 600

Simplifying the equation:

-x = -382

To solve for x, we need to multiply both sides by -1 to change the sign:

(-1)(-x) = (-1)(-382)

Simplifying the equation:

x = 382

Therefore, the solution to the third equation is x = 382.

4) 253 - (x - 459) = 1385

To solve this equation, we need to isolate the variable x. Let's start by simplifying the equation:

253 - x + 459 = 1385
