7x-3y=6,2x=y+3

Solution

7 x - 3 y = 6, 2 x = y + 3

Solution

x = - 3, y = - 9

Solution steps

[7 x - 3 y = 6 2 x = y + 3]

Isolate

x

for

7 x - 3 y = 6 : x = \frac{6 + 3 y}{7}

Substitute

x = \frac{6 + 3 y}{7}

[2 \cdot \frac{6 + 3 y}{7} = y + 3]

Simplify

[\frac{2 ( 6 + 3 y )}{7} = y + 3]

Isolate

y

for

\frac{2 ( 6 + 3 y )}{7} = y + 3 : y = - 9

For

x = \frac{6 + 3 y}{7}

Substitute

y = - 9

x = \frac{6 + 3 ( - 9 )}{7}

\frac{6 + 3 ( - 9 )}{7} = - 3

x = - 3

The solutions to the system of equations are:

x = - 3, y = - 9

x + y + z = 6, 2 x - y + z = 3, x - 2 v + 3 z = 6

2x+3y=8,x-4y=-7

2 x + 3 y = 8, x - 4 y = - 7

3x-2y=14,2x-3y=11

3 x - 2 y = 14, 2 x - 3 y = 11

x=-2+t^2,y=1-2t^2

x = - 2 + t^{2}, y = 1 - 2 t^{2}
