12+9m=-4(-6m-3)
Can some one plz help me and show me how. To do this because I try so many things and got 2different answer
12+9m=-4(-6m-3)
12 + 9m = 24m + 12
0 = 15m
I have another one I don't get its
8-0.03w=1.72w +2.75
8-0.03w=1.72w +2.75
Combine like terms.
8 - 2.75 = 1.72w + 0.03w
To solve the equation 12 + 9m = -4(-6m - 3), we need to simplify both sides of the equation first.
Let's start with the right side of the equation: -4(-6m - 3).
To simplify this, we will use the distributive property, which states that a(b + c) = ab + ac.
So, -4(-6m - 3) becomes: -4 * -6m + -4 * -3.
Multiplying -4 by -6m gives us 24m, and multiplying -4 by -3 gives us 12.
Now our equation becomes: 12 + 9m = 24m + 12.
Next, let's gather the terms with m on one side of the equation, and the constants on the other side.
To do this, we can subtract 9m from both sides of the equation. This cancels out the 9m on the left side, leaving us with:
12 = 24m - 9m + 12.
Simplifying further, we have: 12 = 15m + 12.
Now, let's isolate the term with m by subtracting 12 from both sides of the equation:
12 - 12 = 15m + 12 - 12.
This simplifies to: 0 = 15m.
Now, in order to solve for m, we need to isolate the variable. In this case, since 0 multiplied by any value is still 0, the equation is already solved. This means m can be any value that makes the equation true, as 0 = 15m is always true.
Therefore, the solution to the equation is m = 0.
