3x+9=45 what is the value pf x?

In this equation, 3x + 9 = 45. To solve for x, you need to subtract 9 from both sides of the equation, which gives you 3x = 36. To find the value of x, you need to divide both sides of the equation by 3, which gives you x = 12. Therefore, the value of x is 12.

How do you solve 14 3(3x 3) (x-5)?

To solve the expression ( 14 + 3(3x + 3)(x - 5) ), first simplify the term ( 3(3x + 3) ) by distributing the 3, giving ( 9x + 9 ). Next, multiply this result by ( (x - 5) ) using the distributive property: ( (9x + 9)(x - 5) = 9x^2 - 45x + 9x - 45 = 9x^2 - 36x - 45 ). Finally, combine this with the 14 to get ( 9x^2 - 36x - 45 + 14 = 9x^2 - 36x - 31 ).
