Question

Solve the following pair of linear equation by substitution and cross-multiplication method 8x-5y=9,3x-2y=4

Answer 1

that is your answer

Answer 2

Answer:

x = -2 and y = 5

Step-by-step explanation:

Given Equations are,

8x + 5y = 9

8x + 5y - 9 = 0 ....................(1)

3x + 2y = 4

3x + 2y - 4 = 0 .......................(2)

here,

since,  

There exist unique solution,

By cross multiplication method we get,

First Consider,

Secondly consider,

Therefore, x = -2 and y = 5
