b. y-x=-4
​

tell will explainion tell full example not tell only answer okk

Answer 1

Answer:

Correct option is

A

10

Given, 2x−5=3(x−5)

⇒2x−5=3x−15.

Transpose x terms on one side, we get

⇒3x−2x=−5+15

⇒x=10.

Answer 2

Step-by-step explanation:

x-y=5

x=5+y

y-x=-4

putting x value in these equation,we get

y-(5+y)=-4

y(-5-y)=-4

-5y-y^2=-4

y^2+5y+4=0

y^2+4y+y+4=0

y(y+4)+(y+4)=0

(y+4)(y+1)=0

y=-4 or y=-1

so,x=5+y

=5-4=-1

or x=5-1=4
