Question

How do you solve 3x-15=7x-10

Answer 1

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
