Combine Like Terms:
Combine like terms on the left side of the equation.

Isolate x Terms:
Subtract
4
x
4x
4
x
from both sides to get all the x terms on one side.
\newline
23

6
x
−

x
−

x
23 + 6x - 4x = 4x - 4x

Subtract to Isolate x:
Subtract
23
23
23
from both sides to isolate the
x
x
x
term.
\newline
23

x
−

−
23
\newline
2
x
=
−
23
2x = -23
2
x
=
−
23
Solve for x:
Divide both sides by
2
2
2
to solve for x.
\newline
2
x
2
=
−
