Ok, let’s take it step by step to solve the problem you’ve specified, then the one attached.
2+s/7=2
first, subtract 2 from both sides.
s/7=0
Therefore, s=0. Let’s check our answer.
2+0/7=2
2=2
We can confirm that s=0.
Now, let’s solve the one attached for x.
-2(2x+2)=8
First, use the distributive property and multiply -2 by 2x+2.
-4x-4=8
now, add 4 to both sides.
-4x=12
Finally, divide both sides by -4.
x=-3
Let’s check our answer.
-2(2(-3)+2)=8
-2(-4)=8
8=8, so we can confirm that x=-3.
