i only know #2 because i got it wrong the first time ^^;
NEVER MIND THANK YOU SO MUCH DAMON SUCH A BIG HELP 100% god bless you <3 ;)
does that make 21 or 18?
Keith is right
the same as q - 9 = 12
add 9 to both sides
To find the solution to the equation q + (-9) = 12, we need to isolate the variable q. Here's how:
Step 1: Remove the parentheses:
q - 9 = 12.
Step 2: Move the constant term (-9) to the other side of the equation by adding 9 to both sides:
q - 9 + 9 = 12 + 9.
This simplifies to:
q = 21.
Therefore, the solution to the equation q + (-9) = 12 is q = 21.
