Question

1. Resuelve las siguientes ecuaciones: a. 3x = 33 c. 7x+8 = 64 TRABA b. 5.x - 2 = 33 d. 3x + 7x = 330 f. 11x-22 = 33 e. 7x = 30 + 2x g.17x + 11 = 33+ ​

Answer 1

a. 3x = 33

 x=33/3

 x=11

c. 7x+8 = 64

 7x=64-8

 7x=56

 x=56/7

 x=8

b. 5.x - 2 = 33

 5x=33+2

 5x=35

 x=35/5

 x=7

d. 3x + 7x = 330

 10x=330

 x=330/10

 x=33

f. 11x-22 = 33

 11x=33+22

 11x=55

 x=55/11

 x=5

e. 7x = 30 + 2x

 7x-2x=30

 5x=30

 x=30/5

 x=6
