x-2y=1,2x-4y=2

Solution

x - 2 y = 1, 2 x - 4 y = 2

Solution

x = 1 + 2 y

Solution steps

[x - 2 y = 1 2 x - 4 y = 2]

Isolate

x

for

x - 2 y = 1 : x = 1 + 2 y

Substitute

x = 1 + 2 y

[2 (1 + 2 y) - 4 y = 2]

Simplify

[2 = 2]

The solutions to the system of equations are:

x = 1 + 2 y

[n]yf(y)(y)^2=50[n],f(y)(y)^1=20

[n] y f (y) (y)^{2} = 50 [n], f (y) (y)^{1} = 20

8/x+5/y =-3, 6/x+(25)/y =2

\frac{8}{x} + \frac{5}{y} = - 3, \frac{6}{x} + \frac{25}{y} = 2

y=(2/3)x+4,-2x+3y=6

y = (\frac{2}{3}) x + 4, - 2 x + 3 y = 6

2x+y-2z=1,x-2y+3z=6,3x-3y-z=5

2 x + y - 2 z = 1, x - 2 y + 3 z = 6, 3 x - 3 y - z = 5

x+y/4 =-1,x+y=1

x + \frac{y}{4} = - 1, x + y = 1
