Answer:

Step-by-step explanation:

Solve parenthesis first

Find a common denominator.
The common denominator would be 6.
Because the first expression already has a denominator of 6 it stays the same.


Put that into the original equation.

Isolate the x. Add
to each side.

Find a common denominator.
we can use 18 as the common denominator.

Add.

We cannot simplify so our answer stays the same.
To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22(2x - 10) - 6x = -222x - 6x = -22 +10-4x= -12x= -12/-4x=3
Hope this helps!!!
