Answer:
Set up equation:
Set up the equation from the problem.
\newline
We have the equation
(
x
−
3
)
/
(
x
−
6
)
=
4
/
3
(x-3)/(x-6) = 4/3
(
x
−
3
)
/
(
x
−
6
)
=
4/3
. We need to solve for
x
x
x
.
Cross-multiply:
Cross-multiply to eliminate the
fractions
.
\newline
Cross-multiplying gives us
3
(
x
−
3
)
=
4
(
x
−
6
)
3(x - 3) = 4(x - 6)
3
(
x
−
3
)
=
4
(
x
−
6
)
.
Distribute numbers:
Distribute the numbers on both sides.

x
−
9
=
4
x
−
24
3x - 9 = 4x - 24
3
x
−
9
=
4
x
−
24
Move terms:
Move the variable terms to one side and the constant terms to the other side.
\newline
Subtract
3
x
3x
3
x
from both sides to get
−
9
=
x
−
24
-9 = x - 24
−
9
=
x
−
24
.
Add to isolate:
Add
24
24
24
to both sides to isolate
x
x
x
.
\newline
−
9
+
24
=
x
-9 + 24 = x
−
9
+
24
=
x
