`2y + x = 4x=2y`
To start, express the given as two equations.
EQ1: `2y+x = 4x`
EQ2: `2y = 4x`
Then, let's try to express EQ1 as one variable. To do so, substitute EQ2 to EQ1. So, replace the 2x in EQ1 with 4x.
`2y+x = 4x`
Since all the terms have the x variable, bring them together on one side of the equation.
`4x+x-4x =0`
`x=0`
Then, substitute value of x to either EQ1 or EQ2 and solve for x.
`x = 0` , `2y=4x` `2y=0`
`2y=4*0` `y=0`
Hence, the solution to the given equation is `x=0` and `y=0` .
