timurjin [86]

Answer:x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−3x=8−4x

4+−3x=8+−4x

−3x+4=−4x+8

Step 2: Add 4x to both sides.

−3x+4+4x=−4x+8+4x

x+4=8

Step 3: Subtract 4 from both sides.

x+4−4=8−4

x=4

$undefined$

To find the lowest common multiple (LCM) of 6 and 8, first express the numbers as a product of its prime factors.

$\begin{gathered} 6=2\times3 \\ 8=2\times2\times2=2^3 \end{gathered}$

Next, pick the highest powers for each of the numbers:

$\begin{gathered} \text{LCM}=2^3\times3 \\ =8\times3 \\ =24 \end{gathered}$
