To solve the equation 20=2x-4, you need to isolate the variable x on one side of the equation.
First, add 4 to both sides:
20 + 4 = 2x - 4 + 4
24 = 2x
Then, divide both sides by 2:
24 ÷ 2 = 2x ÷ 2
12 = x
Therefore, x = 12 is the solution to the equation.
First, add 4 to both sides:
20 + 4 = 2x - 4 + 4

12 = x
Therefore, x = 12 is the solution to the equation.
