Question

solve by cross multiplication method
7x-y=23
8x+3y=18​

Answer 1

Step-by-step explanation:

7x-y=23 --(1)

8x+3y=18 --(2)

Multiplying EQ 1 by 3 and EQ 2 by 1, we get

21x-3y=69 --(3)

8x+3y=18 --(4)

Adding EQ 3rd and 4th

29x=87

x = 3

Answer 2

7x-y =23 -------(1)

8x+3y=18--------(2)

Multiplying EQ 1 by 3 and EQ 2 by 1

We get

21x-3y =69-----(4)

8x+3y=18――――(5)

add (3) and (4)

Your solution

x=3

$\star \star \star \star \star$
