Answer:
I think it’s -1.25???? Idk I’m too lazy to check my math
Step-by-step explanation:
You take the 3x and subtract it from both sides. You now have -15 = 4x -10
Then you do +10 to both sides. Now you have -5 = 4x
Divide each side by 4 and you have -1.25 = x
Now check your math.
3 • -1.25 -15 = 7 • -1.25 -10
