Answer:

x=-3 and y=-7

Step-by-step explanation:

[tex]y = 2x - 1[/tex]

[tex]5x - 4y = 1[/tex]

Putting the value of y in Equation

[tex]5x - 4(2x - 1) = 1[/tex]

[tex]5x - 4x + 4 = 1[/tex]

[tex]x + 4 = 1[/tex]

[tex]x = - 3[/tex]

putting the value of x in y equation

[tex]y = 2x - 1[/tex]

[tex] y = 2( - 3) - 1[/tex]

[tex]y = ( - 6) - 1[/tex]

[tex]y = - 7[/tex]
