5x + 3(2x -1) = 3x -14 solve it
Umnica [9.8K]

Answer:

x=-11/8

Step-by-step explanation:

First use the Distributive property on [3(2x-1)]:

5x+6x-3=3x-14

Now combine alike terms:

11x-3=3x-14

Now add three to both sides:

11x=3x-11

Now subtract 3x from both sides:

8x=-11

Now divide both sides by 8:

x=-11/8

This fraction cannot be simplified meaning your final answer SHOULD be -11/8
