Question

x+y=5,2x-3y=4 elimination method
​

Answer 1

We have,

x+y=5---(1)

2x-3y=4---(2)

Now multiply 2 to eq(1)

we get ,2x+2y=10----(3)

subtract eq(3)&(2)

2x+2y=10

2x-3y=4

- - -

__________

5y =6

y=6/5

putting the value of y=6/5 in eq(1)

x+6/5=5

x+6=25

x=25-6

=19

Answer 2

Step-by-step explanation:

X+y=5--(1) 2x-3y=4---(2)

=y=5-x----(3)

sub(3)in (2)

2x-3(5-x)=4

2x-15+3x=4

5x=19

X=19/5---(4)

sub(4) in (1)

19/5+y=5

19+5y=25

5y=25-19

y=6/5

(X=19/5) (y=6/5)
