12-(x+3)=10
12 - 3 - x = 10
9 - x = 10
-x = 10 - 9
x = -1
12-(x+3)=10
first step 12-4x=10
-4x=-2
what is wrong with this step?

Thank you
can you check this problem
15=2(q+4)+3
15=2q+8+3
15=2q+11
4=2q
q=2
thank you so much

You're welcome.
15=2(q+4)+3
15 = 2q + 8 + 3
15 - 11 = 2q
4 = 2q
2 = q
You're right.
