The easiest way to solve this equation is to write an equation and solve for the unknown number. This is the equation:
10
+
6
x
=
4
x
−
4
Subtract each side by 4x.
10
+
2
x
=
−
4
Subtract both sides by 10.
2
x
=
−
14
Divide by 2 on each side to isolate
x
.
x
=
−
7
So you have your answer: the number is
−
7
. To double-check your answer, you can plug this number back into the equation and see if it comes out to be true:
