Question

kardo yar

please solve this by substitution method
5x-8y+20=0
2x+y=10​​

Answer 1

Step-by-step explanation:

(2x+3y=23)×5

(5x−8y=20)×2

Multiplying both the eq.. 1 by 5 and eq. 2 by 2

Then, subtracting them,we get

$\begin{gathered}\begin{gathered}y = 75 \\ x = - 101\end{gathered}\end{gathered}$

y=75

x=−101

y=75

x=−101
