Solve the equation
15x-45=3x

x=3.75

Step-by-step explanation:

15x - 45= 3x

Subtract 15x from both sides:

-45 = -12x

Divide both sides by -12, the -12's cancel and you get:

-45/-12 = 3.75

x= 3.75

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
