What is the solution to the equation? 3x – 6 = –2x + 9 i got 15 is it right
You know you can check by plugging 15 back into the equation, right?
BTW, 15 will not be correct, If you were to show what steps you did, I can help you identify the mistake.
add 2x to both sides of the equation:- 3x + 2x - 6 = -2x + 2x + 9 5x - 6 = 9 add 6 to both sides 5x - 6 + 6 = 9 + 6 5x = 15 x = 3
this one..I can help you... 3x – 6 = –2x + 9 transfer to other side so 3x+2x=6+9 then it is 5x=15 therefore x=3 got it?
