7(5x9)=18-(x+9)
7*45=18 -X -9
315 = 9 - X
X = 9 -315
X = -306

And if you don't believe it, plug -306 into the original equation.

Keep close to Nature's heart... climb a mountain or spend a week in the woods. Wash your spirit clean.* Victims of circumstance owe it to fate. Victims of choice owe it to themselves.*One of the widest gaps in human experience is the gap between what we say we want to be and our willingness to discipline ourselves to get there.

7(5x9)=18-(x+9)

7(45)=18-(x+9)

315=18-(x+9)

315-18=18-18-(x+9) subtract 18 from both sides

297=-(x+9)

-297=(x+9). Multiply both sides by negative 1

-297-9=x+9-9

-306=x

How to solve 9x-4=4(x-1)-5x+4

9x-4=4(x-1)-5x+4 9x -4 = 4x -4 -5x +4 9x -4 = 4x -5x 9x -4 = -1x 10x = 4 x = 0.4 (or 2/5)

Solve for x: (x +7)/ 5 = x/10

(x +7)/ 5 = x/10 Nultiply both sides by 50 to get: 10*(X+7)=5X 10X + 70 = 5X 5X = -70 X = -14 Let us check this answer (put -14 instead of X and see if both sides are equal): (-14+7)/5 = -14/10 -7/5 = -7/5 OK
