Question

5x-2y=1;2x-y=0 came r's rule​

Answer 1

Answer:

x = 1, y = 2

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of y opposite.

(-2). ( 2x - y) = (-2). 0

= -4x + 2y = 0

Simplify.

5x - 2y = 1 (i)

-4x + 2y = 0 (ii)

Add the two equations together to eliminate y from the system.

5x - 2y = 1

+ -4x + 2y = 0

______________

x = 1

Substitute the value found for x into one of the original equations, then solve for y

5x - 2y = 1

5×1 -2y = 1

-2y = 1 - 5

2y = 4

y = 4/2

y = 2

x = 1, y = 2
