5x+2y=7,7x+6y=-3

Solution

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

Solution

x = 3, y = - 4

Solution steps

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

Isolate

x

for

5 x + 2 y = 7 : x = \frac{7 - 2 y}{5}

Substitute

x = \frac{7 - 2 y}{5}

[7 \cdot \frac{7 - 2 y}{5} + 6 y = - 3]

Simplify

[\frac{49 + 16 y}{5} = - 3]

Isolate

y

for

\frac{49 + 16 y}{5} = - 3 : y = - 4

For

x = \frac{7 - 2 y}{5}

Substitute

y = - 4

x = \frac{7 - 2 ( - 4 )}{5}

\frac{7 - 2 ( - 4 )}{5} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 4

5 x + 7 y = 3, 3 x + 14 y = 6

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

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

3x+4y=14,((x-y))/2-((6x+9y))/(10)=-3

3 x + 4 y = 14, \frac{( x - y )}{2} - \frac{( 6 x + 9 y )}{10} = - 3

3x+4y=84,5x+3y=96

3 x + 4 y = 84, 5 x + 3 y = 96

2x+3y=-8,3x-y=-10

2 x + 3 y = - 8, 3 x - y = - 10
