Question

Is 4 + 15x = 49 true? How do you know?

Answer 1

Answer:

Yes it is true.

Step-by-step explanation:

If you go on and solve for x, you get 3. I got this by subtracting the 4 from both sides, then getting 15x=45. Then I divided both sides by 15 and got x=3. If you plug that in, you get 4+45=49. This proves to be true.
