Multiply -3 times the quantity (x+6)
and the equation becomes

-3x -18 +6x = 7x -10

Add -3x and 6x on the left side of the equation

3x -18 = 7x -10

The two sides of the equation are equal, so if you do the same thing to both sides they will still be equal!

Subtract 3x from both sides.

-18 = 4x -10

Add 10 to each side.

-8 = 4x

divide each side by 4

-2 = x so x = -2

Now check by substituting -2 for x in the original equation.

-3(-2+6) +6(-2) = 7(-2) - 10

Adding -2 +6

-3(4) +6(-2) = 7(-2) -10

Multiplying the terms in parenthesis

-12 -12 = -14 -10

Adding the negative terms

-24 = -24

This is true, so the answer x= -2 checks.

Always do a check when possible and correct your mistakes to get the most credit for your work.

It looks this equation is wrong. if you solve this you will get the following.
3x-18=7x-10
If you want to the right hand side=left hand side then it is not possible.

Solving it further you will get
3x-7x-18+10=0
-4x-8=0
-4(x+2)=0
x+2=0
x=-2 is the answer.

-3(x+6)+6x=7x-10  -3x+(-3*6)+6x=7x-10   :-getting 3 inside  -3x+(-18)+6x=7x-10  3x-18=7x-10  -18+10=7x-3x  =>  4x= -8  therefore:-    x= -8 / 4 = -2  i.e x= -2
