Answer 1

Ответ:

1. (68-m)+16=24

  68-m=24-16

   68-m=8

   m=68-8

    m=60

Пошаговое объяснение:

2. 85-(14+n)=68

   14+n=85-68

    14+n=17

    n=17-14

    n=3

3. (524-m)-133=207

   524-m=207+133

   524-m=340

   m=524-340

   m=184

4. 927 - (267 + n) = 349

  267+n=927-349

  267+n=578

  n=578-267

  n=302

Answer 2

To solve these equations, let's go through each one step by step:

1. (68 - m) + 16 = 24 Start by simplifying the left side of the equation: 68 - m + 16 = 24 Combine like terms: 84 - m = 24 Subtract 84 from both sides: -m = -60 Multiply both sides by -1 to solve for m: m = 60

2. 85 - (14 + n) = 68 Start by simplifying the parentheses: 85 - 14 - n = 68 Combine like terms: 71 - n = 68 Subtract 71 from both sides: -n = -3 Multiply both sides by -1 to solve for n: n = 3

3. (524 - m) - 133 = 207 Start by simplifying the left side of the equation: 524 - m - 133 = 207 Combine like terms: 391 - m = 207 Subtract 391 from both sides: -m = -184 Multiply both sides by -1 to solve for m: m = 184

4. 927 - (267 + n) = 349 Start by simplifying the parentheses: 927 - 267 - n = 349 Combine like terms: 660 - n = 349 Subtract 660 from both sides: -n = -311 Multiply both sides by -1 to solve for n: n = 311

5. 67 - (34 + y) + 56 = 73 Start by simplifying the parentheses: 67 - 34 - y + 56 = 73 Combine like terms: 89 - y + 56 = 73 Combine like terms again: 145 - y = 73 Subtract 145 from both sides: -y = -72 Multiply both sides by -1 to solve for y: y = 72

6. 78 + (84 - m) - 13 = 92 Start by simplifying the parentheses: 78 + 84 - m - 13 = 92 Combine like terms: 162 - m - 13 = 92 Combine like terms again: 149 - m = 92 Subtract 149 from both sides: -m = -57 Multiply both sides by -1 to solve for m: m = 57

7. 98 - ((45 + z) - 38) = 42 Start by simplifying the parentheses: 98 - (45 + z - 38) = 42 Combine like terms inside the parentheses: 98 - (83 - z) = 42 Distribute the negative sign inside the parentheses: 98 - 83 + z = 42 Combine like terms: 15 + z = 42 Subtract 15 from both sides: z = 27

8. 69 - (97 - (28 + n)) = 45 Start by simplifying the parentheses: 69 - (97 - 28 - n) = 45 Combine like terms inside the parentheses: 69 - (125 - n) = 45 Distribute the negative sign inside the parentheses: 69 - 125 + n = 45 Combine like terms: -56 + n = 45
