<span>Let's use the quadratic formula:
2w² -</span><span><span> 20w </span>+ 50 = 0</span>
a = 2 b = -20 c = 50
x = -b +-sq root(b^2 - 4*a*c) / 2*a
x = --20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root(400 -4*2*50) / 4
x = 20 +-sq root( 0) / 4
x = 20 / 4 =5
I'd say it has one rational solution.
It does NOT have 2 solutions because the "plus / minus" section = 0.
3/4x+3-2x=-1/4x+1/2x+5
3x+12-8x=-x+2x+20
-5x+12=x+20
-5x-x=20-12
-6x=8
-6x/-6=8/-6
X=8/-6
X=-4/3
Answer:
The first pic is for 2x +3y = 12 and the second is for x=7
