-5(x+3)= -5x-9-5 (-9x+6) multiply first
-5x-15= -5x-9+45x-30 now add or subtract like terms
-5x-15= 40x-39
-45x= -24
x= 24/45= 8/15

-5(x+3)= -5x-9-5 (-9x+6)
Distribute each -5
-5x-15 = -5x-9+45x-30
Combine like terms on the right
-5x-15 = 40x-39
Add 5x to both sides
-15 = 45x-39
Add 39 to both sides
24 = 45x
Divided both sides by 45
24/45 = x
Reduce the fraction
8/15 = x

-5(x+3) = -5x - 9 -5(-9x+6)
-5x-15 = -5x -9 +45x-30 = -39+40x
24 = 45x
x = 24/45 = 8/15

-5x -15 = -5x -9 + 45x -30
then -5x + 5x -45x = 15 -9-30= -24 then
45 x = 24 then x = 24/45 = 8/15

Assume you mean -5(x+3) = -5x - 9 - 5(-9x + 6), then
-5x - 15 = -5x - 9 + 45x - 30, or
-15 + 9 + 30 = -5x + 45x + 5x, or
24 = 45x, or
x = 24/45 = 8/15

-5 (x+3) = -5x - 9 - 5 (-9x+6)
15x - 15 = -5x - 9 + 45x - 30
9 + 30 -15 = 5x - 5x + 45x
24 = 45x
x = 24/45
x = 8/15

-5x - 15 = -5x -9 + 45x - 30
cancel -5x on both sides
-15 = 45x - 39
add 39 on both sides
45x = 24
divide 45 on both sides
x = 24/45, simplified with common factor 3, x = 8/15

-5(x+3)= -5x-9-5 (-9x+6) (simplify multiplication)
-5x-15=-5x-9+45x-30 (add 5x to both sides)
-15=-39+45x (add 39 to both sides)
24=45x
x=24/45
x=0.5333
