8x+4y=-4,10x-4y=4

Solution

8 x + 4 y = - 4, 10 x - 4 y = 4

Solution

x = 0, y = - 1

Solution steps

[8 x + 4 y = - 4 10 x - 4 y = 4]

Isolate

x

for

8 x + 4 y = - 4 : x = - \frac{y + 1}{2}

Substitute

x = - \frac{y + 1}{2}

[10 (- \frac{y + 1}{2}) - 4 y = 4]

Simplify

[- 9 y - 5 = 4]

Isolate

y

for

- 9 y - 5 = 4 : y = - 1

For

x = - \frac{y + 1}{2}

Substitute

y = - 1

x = - \frac{- 1 + 1}{2}

- \frac{- 1 + 1}{2} = 0

x = 0

The solutions to the system of equations are:

x = 0, y = - 1

Popular Examples

y= 1/((x^2)),x=2,x=3

y = \frac{1}{( x ^{2} )}, x = 2, x = 3

-x+2y=1,2x+5y=25

- x + 2 y = 1, 2 x + 5 y = 25

(3/x)/(5/2)=2,x=(3/x)/(5/2)

\frac{\frac{3}{x}}{\frac{5}{2}} = 2, x = \frac{\frac{3}{x}}{\frac{5}{2}}

b^{0.2}x+3y=7,x-y=1

b^{0.2} x + 3 y = 7, x - y = 1

x-4y=10,-2x+y=1

x - 4 y = 10, - 2 x + y = 1
