Answer:

see explanation

Step-by-step explanation:

Given

\frac{\frac{1}{x} }{(\frac{1}{x})^2+1 }

= \frac{\frac{1}{x} }{\frac{1}{x^2}+1 }

Multiply numerator/ denominator by x² to clear the fractions

= \frac{\frac{1}{x}(x^2) }{(\frac{1}{x^2}+1)x^2 }

= \frac{x}{1+x^2}

= \frac{x}{x^2+1}

borishaifa [10]
If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.

Find the substitution 2x+3y=-5 and y=-x+5
tatuchka [14]

Answer: x = 20, y = -15

Step-by-step explanation:

Since we already know that y=-x+5, we can just substitute in that value of y into the other equation:

2x+3y=-5\\2x+3(-x+5)=-5\\2x-3x+15=-5\\-x=-5-15\\-x=-20\\x=20

with the value of x, we can find the value of y:

y=-x+5=-20+5=-15
