Question

can someone please remind this nerd mom how to solve this 6-x-3=10

Answer 1

first, combine like terms on the left side of the equation

Answer 2

\[6-x-3=10\]
\[3-x=10\]

Answer 3

Then subtract 3 from both sides

Answer 4

you end up with
-x=7

Answer 5

so what would it look like written out in the solution steps? Its been a while since I was in school...and my brain needs refreshed :)

Answer 6

6-x-3 = 10
switch position of -x and -3
6-3-x=10
combine like terms
(6-3)=3 so
3 - x= 10 (subtract 9 from both sides to move 3 from left to right)
-3 -3
0 - x= 7
now we need to divide both sides by (-1)
\[\frac{ -x }{ -1 }=\frac{7}{-1}\]
x=-7

Answer 7

Thank you!!
