So far, it is known that the following it true:
y = 4x + 2y = 5x
To make the search for the solution easier, I'll assume that this is based on two different equations:
y = 4x + 2y
and
y = 5x
The first equation can be simplified like so:
y - y = 4x + 2y - y
0 = 4x + y
y = -4x
If you use substitution, the fact that y must equal either -4 times a number or 5 times a number can be used to find the following:
5x = -4x
5x + 4x = 0
9x = 0
x = 0
The only answer to this problem is x = 0 (zero).

2x-3y equals -2 4x plus y equals 24 use substitution method and work the system of equation?
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
What is y equals 4x-10 and y equals 5-x solve using substitution?
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
Y equals 4x minus 8 and y equals 2x plus 10 sole using system of equations using substitution?
y = 4x-8 and y = 2x+10 4x-8 = 2x+10 4x-2x = 10+8 2x = 18 x = 9 Substitute the value of x into the original equations to find the value of y: Therefore: x = 9 and y = 28
What 4x y14 and 2x y8 solve using substitution?
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
-y equals 4x plus 1 4x plus y equals 2?
