7-6x=-15-2(7x+9)
7-6x=-15-14x-18
7-6x=-33-14x
+6x +6x
7=-33-8x
+33 +33
40 = -8x
-5=x

7-6x=-15-2(7x+9); distribute -2
7 - 6x = -15 - 14x - 18; combine like terms
7 - 6x = -14x - 33; add 14x
7 + 8x = -33; subtract 7
8x = -40; divide by 8
x = -5
if you check it both sides equal 37

7 - 6x = - 15 - 14x - 18
14x - 6x = - 33 - 7
8x = - 40
x = - 5

7-6x=-15-2(7x+9) .... Start with the given equation
7-6x=-15-14x-18 .... Distribute
7-6x=-14x-33 .... Combine like terms on the right side
-6x=-14x-33-7 .... Subtract 7 from both sides
-6x+14x=-33-7 .... Add 14x to both sides
8x=-33-7 .... Combine like terms on the left side
8x=-40 .... Combine like terms on the right side
x=(-40)/(8) .... Divide both sides by 8 to isolate x
x=-5 .... Divide
--------------------------------------------------------------
Answer:
So our answer is x=-5
