x-7.(-9)x-15
27x - 5y
To simplify the expression (19x + 12y - 5x + 13y + 75), combine like terms. The (x) terms are (19x - 5x = 14x), and the (y) terms are (12y + 13y = 25y). Therefore, the simplified expression is (14x + 25y + 75).
To simplify the expression (7x + 9 + 12x + 11 + 2y), first, combine the like terms. The terms with (x) are (7x) and (12x), which combine to (19x). The constant terms (9) and (11) combine to (20). Thus, the simplified expression is (19x + 20 + 2y).
To simplify the expression (3(x + 9) - x19), first distribute the 3: (3x + 27). Then, rewrite (x19) as (19x). The expression becomes (3x + 27 - 19x). Combining like terms, we get (-16x + 27).

19x = 437 x = 437 ÷ 19 x = 23
If you mean 4x-19x=50 then x = -3 1/3 or -10/3... Here's how I did it. 4x-19x=50 (4-19=-15) -15x=50 (// -15; divide both sides by -15) x=-50/15 (simplify) x=-10/3 or -3 1/3 If you have any more questions with math related stuff ask away right here (http://www.tutorjam.com/subjects/math_programs.html)!!
19x = 437 x = 437 ÷ 19 x = 23
x^2-19x+90 (x-9) (x-10)
8x - 7 = 15 + 19xsubtract 19x from both sidesadd seven to both sides8x -19x = 15 +7-11x = 22divide both sides by -11x = -2
