Question

Solve the equation 1.2x = 5.16 for x.

Answer 1

1.2x = 5.16
In this expression, x represents a constant number which if multiplied by 1.2, gives 5.16 as an answer.
So to find the number x, we need to divide both sides by 1.2, so we can get only "x" on the first side. 1.2x/1.2 = x
so x = 5.16/1.2
x=4.3

Re-check your answer, and you'll find that 1.2*4.3 = 5.16

Hope this helps! :)

Answer 2

1.2x = 5.16

x = 5.16/1.2

x = 4.3
