Can you please explain how to do this equation, thanks
x+9+12 = -3
x+9+12 = -3
We need to get the known numbers on one side of the equation. To do this we have to subtract the known numbers from both sides.
x + 9 + 12 - 9 - 12 = -3 -9 -12
x = -24
Check it by substituting -24 for x.
Thank you Ms. Sue :-)
Of course! To solve the equation x + 9 + 12 = -3, you need to isolate the variable x on one side of the equation.
Step 1: Combine like terms on the left side of the equation.
x + 9 + 12 simplifies to x + 21, so the equation becomes x + 21 = -3.
Step 2: Move the constant term to the right side of the equation.
To do this, subtract 21 from both sides of the equation.
x + 21 - 21 = -3 - 21
This simplifies to x = -24.
So, the solution to the equation x + 9 + 12 = -3 is x = -24.
