Question

plz substitute the following equations
5x + 2y = 13 .... 1)
4x - 3y = 15 .... 2)​

Answer 1

x= (13-2y)/5

Or

x= (15+3y)/4

Or

y= (13-5x)/2

Or

-y= (15-4x)/3

Answer 2

step1-___

5x+2y-13=0

4x-3y-15=0

step2__

take 'y' coffecient and constant ,then x coffecient put them side by side and same y coffecient

step3____

x y 1

2 -13 5 2

-3 -15 4 -3

step4___

do cross multiply

X/-30-39 ,Y/-52+75 , 1/-15-8

X/-69, Y/23, 1/-23

step 5____

therefore,X= -69/-23

Y=23/-23

》》(x,y)=(3,-1)
