Answer :

Let's solve the equation step by step:

Given equation:
[tex]\[ 2x \cdot 4 = 20 \][/tex]

First, simplify the left-hand side by multiplying the constants:
[tex]\[ 2 \cdot 4 = 8 \][/tex]

So the equation becomes:
[tex]\[ 8x = 20 \][/tex]

Next, we need to solve for [tex]\( x \)[/tex] by isolating it. To do this, we divide both sides of the equation by 8:
[tex]\[ x = \frac{20}{8} \][/tex]

Now, we simplify the fraction:
[tex]\[ x = \frac{20}{8} = 2.5 \][/tex]

Therefore, the solution to the equation [tex]\( 2x \cdot 4 = 20 \)[/tex] is:
[tex]\[ x = 2.5 \][/tex]

This completes our step-by-step solution.
