Answer:
x = 21, y = 2
Step-by-step explanation:
4x- 3y = 78....(1)
2x + 3y = 48 ...(2)
Adding eqiautions (1) and (2)
4x- 3y = 78
2x + 3y = 48
-----------------------
6x + 0 = 126....(Here y has been eliminated)
6x = 126
[tex] x= \frac{126}{6}\\\\
\therefore x = 21\\[/tex]
Plugging x = 21 in equation (2) we find:
2 * 21 + 3y = 48
42 + 3y = 48
3y = 48 - 42
3y = 6
[tex] y= \frac{6}{3}\\\\
\therefore y = 2\\[/tex]
