Answer:
x=2 , y=1
Step-by-step explanation:
3x+4y=10....eq1
4x-3y=5......eq2
by multiple 3 in eq1 and 4 in eq2
=3(3x+4y=10)
4(4x-3y=5)
=9x+12y=30
16x-12y=20
by cutting +12y with -12y we get
9x+16x=30+20
25x=50
x=50/25
x=2
putting the value of x in eq1
3x+4y=10
3(2)+4y=10
6+4y=10
4y=10-6
4y=4
y=4/4
y=1
