Answer 1

Explicación paso a paso:

1)

a)3x-6 = 3

3x = 3+6

3x = 9

x = 9/3

B)-1+2x=9-3x

2x+3x = 9+1

5x = 10

x = 10/5

x = 2

2)

a)3x/2 = 6

3x = 2(6)

3x = 12

x = 12/3

x = 4

b)(4x-6)/3 = -2

(4x-6) = (-2)3

4x - 6 = -6

4x = -6+6

4x =0

x = 0/4

x=0

3)

a)7x - (1-2x)/4 = 11

4(7)x - (1-2x) = 11(4)

28x - (1-2x) = 44

28x -1 +2x =44

28x +2x = 44+1

30x = 45

x = 45/30

x = 3/2

b)(3x+2)/5    +  (x-3)/2  = 0

2(3x+2) + 5(x-3) = 0

6x + 4 + 5x - 15 =0

6x +5x = 15-4

11x = 11

x = 11/11

x =1
