If that's -144, the answer is (5x + 12)(5x - 12)
5x
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
x^2 -5x-6 factors to: (x-6)(x+1)
(x - 4)(x + 9)
5x-19 = 16 5x = 16+19 5x = 35 x = 7
5x+1=20 5x=20-1 5x=19 5x/5=19/5 x=19/5
You do not.
5X - 19 = 16 add 19 to both sides 5X - 19 + 19 = 16 + 19 5X = 35 divide each sides integers by 5 (5/5)X = 35/5 X = 7 ---------------check in original equation 5(7) - 19 = 16 35 - 19 = 16 16 = 16 ------------checks
8x - 19 = 3x + 1 5x -19 = 1 5x = 20 x = 4
it is 45
Can you help me find the value x & Y 3x + 7y = 5 5x-2y = -19
x=19.
-5x + 7y = 11 (1) -5x + 3y = 19 (2) Subtract (2) from (1) 4y = -8 divide both sides by 4 y = -2 (the y-coordinate of the solution point) Replace -2 for y at one of the given equations, let's say at (2). -5x +3(-2) = 19 -5x - 6 = 19 add 6 to both sides -5x = 25 divide both sides by -5 x = -5 (the x-coordinate of the solution point) Thus, the solution point is (-2, -5).
5x + 5y = 19x = 3.8 - yory = 3.8 - x
In the equation 43X +2=5X, X=-1/19.
x = 2, y = 1
