Question

1. Selecciona la respuesta o solución adecuada a cada ecuación. a. 4u – 10 = 50; u = 5, u = 15 b. 9y + 12 = 48, y = 4, y = 6 c. 5n + 24 = 4, n= 3,n = - 4 d. 1/3 p +8 = 10; p= - 2, p = 6 e. 4a – 12 = 50; a = 31/2, a = - 31/2 f. 16 b + 30 = 78; b = 4, b = 3 g. 3 c + 24 = 48 ; c = 23, c= 8

Answer 1

Respuesta:

a) 4u-10=50

4u=50+10

u= 60/4=15

u = 15

b) 9y+12=48

9y = 48-2

9y = 36

y = 36/9 =4

y=4

c) 5n+24= 4

5n =4 - 24

5n = - 20

n= - 20/5

n= - 4

d) 1/3p +8= 10

p +24 =30

p = 30-24

p = 6

e) 4a-12 =50

4a= 50+12

a = 62/4

a = 31/2

f) 16b+30= 78

16b = 78-30

16b= 48

b= 48/16

b= 3

g) 3c+24= 48

3c = 48-24

3c = 24

c = 24/3

c= 8
