Kindly check explanation
Step-by-step explanation:
Given the equation : 2x-4=20
By adding 4 1 - tiles to each side, this will eleminate the constant term on the left hand side where the Coefficient we wish to solve for lies. Hence, the same exact treatment given to data on the right hand side is done to the data in the left. Hence, the method will work as it will give ;
2x - 4 = 20
2x - 4 + 4 = 20 + 4
2x = 24 ( constant eliminated)
x = 24/4
x = 6
