1) 133 + x + 57 = 218

x + 190 = 218

x = 218 - 190

x = 28

2) 248 - (y + 128) = 24

248 - y - 128 = 24

120 - y = 24

-y = 24 - 120

-y = -96

y = 96

3) (24 - x) + 39 = 49

63 - x = 49

-x = 49 - 63

-x = -14

x = 14

4) (y + 267) - 97 = 538

y + 267 - 97 = 538

y + 170 = 538

y = 538 - 170

y = 368

5) 163 + (87 + n) = 303

163 + 87 + n = 303

250 + n = 303

n = 303 - 250

n = 53

6) (x - 24) - 56 = 134

x - 24 - 56 = 134

x - 80 = 134

x = 134 + 80

x = 214

Пошаговое объяснение:

1) 133 + x + 57 = 218

To solve this equation, we can simplify it by combining like terms:

x + 190 = 218

Next, we isolate the variable x by subtracting 190 from both sides:

x = 218 - 190

x = 28

2) 248 - (y + 128) = 24

To solve this equation, we can simplify it by distributing the negative sign:

248 - y - 128 = 24

Combine like terms:

120 - y = 24

Next, we isolate the variable y by subtracting 120 from both sides:

-y = 24 - 120

-y = -96

Divide by -1 to solve for y:

y = 96

3) (24 - x) + 39 = 49

To solve this equation, we can simplify it by combining like terms:

63 - x = 49

Next, we isolate the variable x by subtracting 63 from both sides:

-x = 49 - 63

-x = -14

Divide by -1 to solve for x:

x = 14

4) (y + 267) - 97 = 538

To solve this equation, we can simplify it by combining like terms:

y + 267 - 97 = 538

Combine like terms:

y + 170 = 538

Next, we isolate the variable y by subtracting 170 from both sides:

y = 538 - 170

y = 368

5) 163 + (87 + n) = 303

To solve this equation, we can simplify it by combining like terms:

163 + 87 + n = 303

Combine like terms:

250 + n = 303

Next, we isolate the variable n by subtracting 250 from both sides:

n = 303 - 250

n = 53

6) (x - 24) - 56 = 134

To solve this equation, we can simplify it by combining like terms:

x - 24 - 56 = 134

Combine like terms:

x - 80 = 134

Next, we isolate the variable x by adding 80 to both sides:

x = 134 + 80

x = 214
