Question

solve the equation 4x-5y+16=0 and 2x+y-6=0 not using graphical method​

Answer 1

Step-by-step explanation:

we. can sove this by elimination method

Answer 2

On solving the equations 4x - 5y + 16 = 0 and 2x + y - 6 = 0 not using graphical method, we get

x = 1

y = 4

Given:

Equations:

4x - 5y + 16 = 0

2x + y - 6 = 0

To find:

The value of x and y by solving this equation without using graphical method.

Solution:

We are given the equations:

4x - 5y + 16 = 0 ---(1)

2x + y - 6 = 0 ---(2)

Multiplying equation (2) with 5, we get

10x + 5y - 30 = 0 ---(3)

Adding the equations (1) and (3), we get

(4x - 5y + 16) + (10x + 5y - 30) = 0

=> 14x - 14 = 0

=> 14x = 14

=> x = 1

Substituting the value of x in equation (2), we get

2(1) + y - 6 = 0

=> 2 + y - 6 = 0

=> y - 4 = 0

=> y = 4

Hence,

x = 1

y = 4
