Multiply both sides by (x-2)(x+1) to clea fractions
x(x+1)+(x-1)(x-2)=(-1)(x-2)(x+1)
distribute
x^2+x+x^2-3x+2=-x^2+x-2
add like terms
2x^2-2x+2=-x^2+x+2
add x^2 to both sdes
3x^2-2x+2=x+2
minus x from both sides
3x^2-3x+2=2
minus 2 both sides
3x^2-3x=0
factor
(3x)(x-1)=0
set to zero

3x=0
x=0

x-1=0
x=1

Plz help <br> Find ‘x’ &amp; ‘y’
just olya [345]

Answer:

x=20. y=15

Step-by-step explanation:

in similar triangles the sides are all in proportion. this means:

\frac{25}{5}  =  \frac{x}{4}  =  \frac{y}{3}

\frac{25}{5}  = 5

so:

\frac{x}{4}  = 5

x=5×4

x=20

and...

\frac{y}{3}  = 5

y=3×5

y=15
