Question

4 Halla x en cada caso:
a) 4x = 3x + 5
d) 3x = 9x + 12
g) 4 - 2x = 3x
b) 5x = 7x – 4
e) 8x = 5x + 2
h) 2 + 6x = 9x
c) 2x = 7 x – 5
f) 3x = 9x – 5
i) 5 – 6x = -X​

Answer 1

Explicación paso a paso:

a) 4x - 3x = 5 》x = 5

d) 9x - 3x= -12 》 6x = -12 》 x = -2

g) 3x + 2x = 4 》5x = 4 》x = 4/5

b) 7x - 5x = 4 》2x = 4 》 x = 2

e) 8x - 5x = 2 》3x = 2 》 x = 2/3

h) 9x - 6x = 2 》3x = 2 》 x = 2/3

c) 7x - 2x = 5 》5x = 5 》 x = 1

f) 9x - 3x = 5 》6x = 5 》 x = 5/6

i) 6x - 1x = 5 》5x = 5 》 x = 1
