Question

solve pair of lenear equation 2x+3y=1 and 2x-4y =24​

Answer 1

Answer:

y= -23/7, x=5.428

Step-by-step explanation:

solve the linear equation

2x +3y =1 this is the equation 1

2x -4y =24 this is the equation 2

- + -

7y = -23

y = -27/7

put the y value in equation 1

2x + 3y = 1

2x + 3(-23/7) = 1

2x - 69/7 =1

14x -69 /7 = 1

14x - 69 = 7

14x = 7 +69

x = 76/14

x = 5.42
