We may determine the option a) 15x - 12 by simply multiplying and adding them by the necessary terms.
A linear equation is an algebraic equation of the form y = mx + b. involving only a continuing and a first-order ( linear ) term, where m is the slope and b is the y-intercept.
5X ( 3 - 12 X) - 3 ( 4 - 20[tex]x^{2}[/tex] )
15X - 60[tex]x^{2} \\[/tex] - 3 ( 4 - 20[tex]x^{2}[/tex] )
15X - 60[tex]x^{2} \\[/tex] - 12 + 60[tex]x^{2}[/tex]
15X - 12 this is required solution .
Just by simply multiplying and adding them by required terms we can conclude 15x - 12.
