x-7.(-9)x-15
27x - 5y
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).
-11
19x = 437 x = 437 ÷ 19 x = 23
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)!!
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
