3x+2y=7,x+3y=0

Solution

3 x + 2 y = 7, x + 3 y = 0

Solution

x = 3, y = - 1

Solution steps

[3 x + 2 y = 7 x + 3 y = 0]

Isolate

x

for

3 x + 2 y = 7 : x = \frac{7 - 2 y}{3}

Substitute

x = \frac{7 - 2 y}{3}

[\frac{7 - 2 y}{3} + 3 y = 0]

Simplify

[\frac{7 + 7 y}{3} = 0]

Isolate

y

for

\frac{7 + 7 y}{3} = 0 : y = - 1

For

x = \frac{7 - 2 y}{3}

Substitute

y = - 1

x = \frac{7 - 2 ( - 1 )}{3}

\frac{7 - 2 ( - 1 )}{3} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 1

x-y=2,5sqrt(x)+sqrt(y)=25

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

x+y+z=1,2x+3y+6z=4,4x-3y-12z=8

x + y + z = 1, 2 x + 3 y + 6 z = 4, 4 x - 3 y - 12 z = 8

- 5 x + 4 y = - 3, 8 x + 3 y = - 3

15x+10y=10,8x-10y=20

15 x + 10 y = 10, 8 x - 10 y = 20
