Answer:
x = 2
Step-by-step explanation:
Equation: 5x(4 - 2) = 20
Simplify: 5x(2) = 20
Simplify: 10x = 20
Divide: x = 2
For this case we must find the value of the variable "x" of the following equation:
[tex]5x (4-2) = 20[/tex]
We solve the operation within the parenthesis:
[tex]5x (2) = 20[/tex]
We multiply the left side:
[tex]10x = 20[/tex]
We divide both sides of the equation by 10:
[tex]x = \frac {20} {10}\\x = 2[/tex]
ANswer:
[tex]x = 2[/tex]
