Question

2x+y=4 elimination 5x-3y=1 pls solve porepr ​

Answer 1

Answer:

x = 13/11

y = 18/11

Step-by-step explanation:

(2x + y = 4) × 3 ------- (i)

6x + 3y = 12 ----- (ii)

5x - 3y = 1 ------ (iii)

Using Elimination method,

Add (ii) and (iii),

6x + 3y + 5x - 3y = 12 + 1

11x = 13

$x=\frac{13}{11}$

5x - 3y = 1

$5(\frac{13}{11} ) - 3y = 1\\\\\frac{65}{11} -3y =1\\\\3y=\frac{65}{11} -1\\\\3y=\frac{65-11}{11} \\\\y=\frac{54}{33}\\\\y=\frac{18}{11}$
