Question 667466

 Can you please help me? 3d+8= 2d-7
I Did 3d plus 2d because there like terms. Which makes 5d+8=-7?
Then i did -7 minus 8 which equals -1 so it becomes 5d=-1? Then 5d divided by -1 equals -5?
Am i doing this right? If not can you please help me do it right?


No, you're not doing it right!!


3d + 8 = 2d - 7
3d - 2d + 8 = - 7 ----- Subtracting 2d to make it 0 on right side, and also subtracting it on left-side


3d - 2d = - 7 - 8 ----- Subtracting 8 to make it 0 on left side, and also subtracting it on right-side
