Question

4. Resuelva las ecuaciones
a. 7 + x = 24
b. 4x = 48
C. x - 2 = 20
d. 4x + 10 = 30​

Answer 1

Respuesta:

a. 17

b. 12

c. 22

d. 5

Explicación paso a paso:

a. 7 + x = 24

x = 24 - 7

x = 14

b. 4x = 28

x = 28/4

x = 12

c. x - 2 = 20

x = 20 + 2

x = 22

d. 4x + 10 = 30

4x = 30 - 10

4x = 20

x = 20/4

x = 5
