Question

a) 2x - 7 = 5x + 2
b) 3 + 3x – 1= x + 2 + 2x
c) 3x + 1 = 3 - (2-2x)
d) 2. (3x - 2) = 2
e) 10- x = 5(x - 2)

me pueden ayudar. gracias ​

Answer 1

Respuesta:

a)2x - 7 = 5x + 2

2x - 5x = 2 + 7

-3x = 9

x = 9÷(-3)

x = -3

b)3 + 3x - 1 = x + 2 + 2x

3x - x - 2x = 2 - 3 + 1

0x = 0

x = 0

c)3x + 1 = 3- (2-2x)

3x +1 = 3 - 2 +2x

3x -2x = 3 - 2 -1

1x = 0

x = 0

e) 10 -x = 5 (x-2)

10 - x = 5 x + 2

x - x = 5 - 10

0x = 5

x = 0
