Question

8x+5y=9 3x+2y=4 maths slove question answer

Answer 1

Answer:

X = -2

Y= 5

Step-by-step explanation:

→ Solving the given equation By Elimination method :

8x+5y=9 __________ (1)

3x+2y=4 __________ (2)

→ Multiplying the equation (1) by 2 & equation (2) by 5.

We get,

16x+10y = 18

15x+10y= 20

→ Subtracting both the equations.

We get,

x = -2

→ Putting the value of x in equation (1).

8(-2) +5y = 9

-16+5y = 9

5y = 9+16

5y = 25

y = 25/5

y = 5

Answer 2

Solution:-

Given Equations:-

8x+5y=9 ---------(1)

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

To Find :-

x = ?

y = ?

Find:-

By Elimination Method,

Multiplying Eq (1) by 2 and Eq (2) by 5.

=) 16x + 10y = 18

=) 15x + 10y = 20

_______________

=) x. = -2

Putting [ x = -2 ] in eq (2). we get,

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

=) -6 + 2y = 4

=) 2y = 10

=) y = 5

Hence,

x = -2 and y = 5.
