Question

4x-2y=5 and 2x-y=10 solve by substitution methode​

Answer 1

Given:

$4x-2y=5\\2x-y=10$

To find:

The value of x and y

By using substitution method:

Solve for y

$2x-10=y$

$2x-y=2x-10-2x$    [Subtract 2x from both side]

$y=2x-10$

$y=2x-10$

Substitute value of y in the equation

$4x-2(2x-10)=5$

Multiply 2 with bracket,

we get

$4x-4x+20=5$

$20=5$

Subtract 20 on both sides

$0=-15$
