my sister thinks i dont know how to solve it
2007-12-30 14:11:05 · 12 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
3x=6x+45
(subtract 3x from both sides)
0=3x+45
(subtract 45 from both sides)
-45=3x
(divide both sides by 3)
-15=x
Hope that helped!

3x -6x =45
-3x=45
x= -15

0=x+15 devide through by 3
x=-15 subtract 14 from each side

Move the 6x over...
-3x = 45
Divide both sides by -3 to get rid of the -3 in front of x...
x = -15

3x=6x+45
First you get the variable x to one side of the equation
-3x=45
Then you divide both sides by -3
x= -15

6x + 45 = 3x
6x = 3x - 45
3x = - 45
x = - 15
