Answer 1

a) 3x + 6 = x - 2

4x = -8

x = -2

b) 5(2 - x) = 3(x + 1)

10 - 2x = 3x + 3

7 = 5x

7 / 5 = x

c) 2x + 4 - 7x = -x + 9

2x = -8x + 5

10x = 5

x = 0.5

x = 5 / 10

d) ( 5x - 7 ) / 2 = 8x - 9

5x - 7 = 16x - 18

-11x = -18 + 7

-11x = 11

x = 1

e)

7 ( 4x - 8 ) = 3 ( 5x - 1 )

28x - 56 = 3 ( 5x - 1 )

13x = 53

x = 53 / 13

f) 3 ( 2x - 2 ) = 2 ( 3x + 9 )

6x - 6 = 6x + 18

-6 = 18

= 24

( "x" NO existe )

g) 2 ( x + 4 ) - 10 ( 25 - x + 4 ) = 5 -3x - 4 ( x + 1 )

( 2x + 8 ) - ( 250 - 10x + 40 ) = 5 - 3x - 4x + 4

( 2x + 8 ) - (290 -10x ) = 9 - 7x

12x - 282 = 9 - 7x

19x = 291

x = 15.31

x = 291 / 19
