$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Step-by-step explanation:

MULTIPLE EQUATION 1 WITH 5 BOTH THE SIDE:--

$3 \times 5x + 4 \times5y = 18 \times 5$

$15x + 20y = 90......1st \: equation$

_______________________________

multiple EQUATION 2 with 4 both the side

$4 \times 4x + 5 \times 4y = 23 \times 4$

$16x + 20y = 96$

_______________________________

NOW SUBSTRATE EQ 2 WITH EQ 1

$16x + 20y - 15x - 20y = 96 - 90$

$x = 6$
