You can put this solution on YOUR website! Question:
3x – 7 = 2x + 8
Answer:
3x – 7 = 2x + 8
subtract 2x from both sides...
==> 3x - 2x - 7 = 2x - 2x + 8
==> x - 7 = 8
Add 7 on both sides.....
==> x - 7 + 7 = 8 + 7
==> x = 15
To check you solution, plugg the value of x, that is x = 15 in the given equation.....
3 * 15 – 7 = 2* 15 + 8
==> 45 - 7 = 30 + 8
==> 38 = 38
That is you have got same value on both sides of the equal sign.
So your answer is correct.
Hope you found the explanation useful.
Warm Regards.
