Question

3x-2y=5,5x-y=3 by comperision method​

Answer 1

Answer:

Solution

Step-by-step explanation:

Solve equation [2] for the variable y

[2] y = 5x - 3

// Plug this in for variable y in equation [1]

[1] 3x - 2•(5x-3) = 5

[1] -7x = -1

// Solve equation [1] for the variable x

[1] 7x = 1

[1] x = 1/7

// By now we know this much :

x = 1/7

y = 5x-3

// Use the x value to solve for y

y = 5(1/7)-3 = -16/7
