Answer 1

Respuesta:

Horizontales:

1) x + 17 = 52

x = 52 - 17

x = 35

2) 2y - 200 = 42

2y = 42 + 200

2y = 242

y = 242/2

y = 121

4) = 576

y = 24

5) 2x/5 = 16

2x = 16 * 5

2x= 80

x = 80/2

x = 40

7) 3a - 3 = 114

3a = 114 + 3

3a = 117

a = 117/3

a = 39

8) y/8 + 12 = 20

y/8 = 20 - 12

y/8 = 8

y = 8 * 8

y = 64

10) x/9 + 64 = 100

x/9 = 100 - 64

x/9 = 36

x = 36 * 9

x = 324

11) 4x + 5 = 89 + 8

4x = 89 + 8 - 5

4x = 97 - 5

4x = 92

x = 92/4

x = 23

Verticales:

1) x/6 + 7 = 12

x/6 = 12 - 7

x/6 = 5

x = 5 * 6

x = 30

3) 8n + 50 = 850

8n = 850 - 50

8n = 800

n = 800/8

n = 100

4) 6a - 11 = 109

6a = 109 + 11

6a = 120

a = 120/6

a = 20

6) x/7 = 49

x = 49 * 7

x = 343

7) 2y + 12 = 80

2y = 80 - 12

2y = 68

y = 68/2

y = 34

8) 4n - 6 = 250

4n = 250 + 6

4n = 256

n = 256/4

n = 64

9) 2x - 100 = 26

2x = 26 + 100

2x = 126

x = 126/2

x = 63
