Answer
2.(2,1)
3. (2,2)
Step-by-step explanation:
Given,
2.2x+y=4
x+3y=_3
sol
2x+y=4..... equation i
x+3y=_3 ....eq ii
eq ii of 2 multiple the eq i
2x+y=4
2x+6y=_6
_ _ +
__________
o+ 5y = 10
y =10÷5
y = 2 ans
y valu put the eq 1
2x+y=4
2x+2=4
2x=4_2
2x=2
x=2÷2
x=1
3.
sol
3x+5y=4..... eq 1
x+3y=4 ..... eq 2
eq 2 multiple eq 1. 3
3x+5y=4
3x+9y=12
_ _ _
___________
0x+4y=8
4y=8
y=8÷4
y=2 ans
the y value put the eq 1
3x+5y=4
3x+5×2=4
3x+10=4
3x=10_4
3x=6
x=6÷3
×=2 ans
