What is the solution of the following system of equations ? y- 2x and= 6 , y - 4x =0

Sveta_85 [38]

Answer:

x=3 and y=12

Step-by-step explanation:

$y-2x=6$ equation:1

$y-4x=0$ equation:2

Solving equation:1 for 'y' in terms of x

$y=6+2x$ equation:3

Putting 'y' in equation:2 which will make the equation of the single variable

$y-4x=0$

$6+2x-4x=0\\-2x=-6\\x=3$

Putting value of 'x' in equation:3 to find 'y'

$y=6+2x$

$y=6+2(3)\\y=6+6\\y=12$
