Question

What value of x makes this equation true ? -6x+3=45

Answer 1

Answer:

x = -7

Step-by-step explanation:

-6x + 3 = 45

First, we need to get rid of the 3 by subtracting it by 3. We need to do the same to the number on the other side.

-6x + 3 = 45

      -3    -   3

-6x = 42

Then, to iolate the x, we need to divide -6 by itself to cancel the number out and get x alone. We also need to divide 42 by -6 as well.

$\frac{-6x}{-6} = \frac{42}{-6}$

42 divided by -6 is -7.

$x=-7$

I hope this helps!
