Question

alguen me ayuda a) 2+3×= -1 b) ×-3=2(×-1) d) 4(× + 1) -6=(×+3)

Answer 1

2 + 3x = - 1

3x = - 1 - 2

3x = - 3

x = -3/3

x = - 1
----------------------

x - 3 = 2 (x - 1)

x - 3 = 2x - 2

x - 2x = - 2 + 3

- x = 1

x = - 1
-----------------------

4 (x + 1) - 6 = (x + 3)

4x + 4 - 6 = x + 3

4x - 2 = x + 3

4x - x = 3 + 2

3x = 5

x = 5/3
