Answer 1

Respuesta:

7

Explicación paso a paso:

Answer 2

2(m + 6)=10

2m + 12 = 10

2m = 10-12

2m = -2

m = -2/2

m = -1

5(n+8)=65

5n + 40 = 65

5n = 65-40

5n = 25

n = 25/5

n = 5

7(y+4)=84

7y + 28 = 84

7y = 84-28

7y = 56

y = 56/7

y = 8

4(x+9)=72

4x + 36 = 72

4x = 72-36

4x = 36

x = 36/4

x = 9

3(z-6)=36

3z - 18 = 36

3z = 36+18

3z = 54

z = 54/3

z = 18

6(x-4)=126

6x - 24 = 126

6x = 126+24

6x = 150

x = 150/6

x = 25

9(w-10)=108

9w - 90 = 108

9w = 108+90

9w = 198

w = 198/9

w = 22

12(x-5)=72

12x - 60 = 72

12x = 72+60

12x = 132

x = 132/12

x = 11
