What value of x makes this equation true ? -6x+3=45
Sveta_85 [38]

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

-<em>6x = 42</em>

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!

What’s the least common denominator of 8,12
IceJOKER [234]

Answer: 24

Step-by-step explanation:

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Hope this helps!!! Good luck!!! :)
