3(2x-y)=9,2(x+y)=0

Solution

3 (2 x - y) = 9, 2 (x + y) = 0

Solution

x = 1, y = - 1

Solution steps

[3 (2 x - y) = 9 2 (x + y) = 0]

Isolate

x

for

3 (2 x - y) = 9 : x = \frac{3 + y}{2}

Substitute

x = \frac{3 + y}{2}

[2 (\frac{3 + y}{2} + y) = 0]

Simplify

[3 + 3 y = 0]

Isolate

y

for

3 + 3 y = 0 : y = - 1

For

x = \frac{3 + y}{2}

Substitute

y = - 1

x = \frac{3 - 1}{2}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = - 1

Popular Examples

(2) x + y = 5, x - y = 3

x + y = 3, 2 x - y = 12

-x+y=-1,-2x+4y=-8

- x + y = - 1, - 2 x + 4 y = - 8

2x+4y+8z=0,x+2y+3y=0,x=0

2 x + 4 y + 8 z = 0, x + 2 y + 3 y = 0, x = 0

((2x+5y))/((xy))=6,((4x-5y))/((xy))=-3

\frac{( 2 x + 5 y )}{( x y )} = 6, \frac{( 4 x - 5 y )}{( x y )} = - 3
