Question

[tex] x+y-8=0,2x-3y-1=0
find out x and y.





*

Answer 1

3×eq(1)
3x+3y=24...... eq (3)
eq(2)+(3)
5x=25
x=5
put in eq3(1)
5+y=8
y=3
x=5 and y=3
is your answer

Answer 2

Hey

Here is your answer,

x+y=8
Multiplying the equation by 2,
2x+2y=16
__________eq.1

2x-3y=1
__________eq.2

Solving both the equations by elimination method,

2x+2y=16

2x-3y =1
________
5y=15
Y=15/5
Y=3

To find the value of x :

X+y-8=0
X+3-8=0
X-5=0
X=5

Hope it helps you!
