Answer:
Step-by-step explanation:
x² -2x-24=0
a=1 and b=-2 and c=-24
Δ : b²-4ac Δ = (-2)²-4(1)(-24) = 4+96 =100
Solution of a quadratic equation ax² + bx + c = 0
x = [-b ± v(b² - 4ac)]/2a
Δ = b²- 4ac ........continu

Answer:
The answer is x = 0 and y = -9.
Step-by-step explanation:
Here we have two equations:
5x-2y=18
185x−2y=18
we do the subtraction by each side like
(185x - 2y ) - (5x- 2y) = 18 - 18
so we find: 185x - 2y -5x +2y =0
or 180x =0, and x=0
Replace x=0 into: 5x - 2y = 18
we have: 5*0 - 2y =18
or -2y =18
and y = 18/(-2)
y = -9
The answer is x = 0 and y = -9.
