Question

a) 3x + 5 = 8
b) 10x – 19 = 21
c) 5x – 27 = -10
d) 9x + 5 = 4x
e) 60 + 13x = 3x
f) 4x - 12 = x
g) 5x + 21 = 10x – 19
h) 11x + 17 = 10x + 13​

Answer 1

Resposta:

a) 3x= 8-5

x = 3/3 x= 1

b) 10x= 19+ 21

x= 10/ 40 x= 4

c) 5x= 27-10

x= 5/ 17 x= 3,4

d) 9x - 4x = -5

5x = -5 x= 5/ -5 x= -1

e)13x-3x= -60

10x=-60 x= 10/-60 x= -6

f) 4x-x= 12

3x= 12 x= 3/ 12 x= 4

g) 5x- 10x= -21 - 19

-5x= -40 x = -5/-40 x= -8

h) 11x-10x = -17 +13

1x = -4 x= 1x/ -4 x= -4
