Step-by-step explanation:
start by adding together the numbers in the right hand column
I think you want me to solve for k
expanding, you get
24k-9=-42+24k
which is clearly no solution
-q-7q=8
First you need to know that there is an invisible 1 in front of -q. Change it to -q if you need to. You get:
-1q-7q=8
add like terms: -1-7 gives you -8.
-8q=8. Divide by -8 on both sides to find q.
-8/8=-1
8/8=1
Therefore, q=1.
