3x-2y=-7,4x-y=-6

Solution

3 x - 2 y = - 7, 4 x - y = - 6

Solution

x = - 1, y = 2

Solution steps

[3 x - 2 y = - 7 4 x - y = - 6]

Isolate

x

for

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

Substitute

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

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

Simplify

[\frac{- 28 + 5 y}{3} = - 6]

Isolate

y

for

\frac{- 28 + 5 y}{3} = - 6 : y = 2

For

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

Substitute

y = 2

x = \frac{- 7 + 2 \cdot 2}{3}

\frac{- 7 + 2 \cdot 2}{3} = - 1

x = - 1

The solutions to the system of equations are:

x = - 1, y = 2

x-y=20,8x-8y=160

x - y = 20, 8 x - 8 y = 160

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

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

5x-2y=13,x=-3y+6

5 x - 2 y = 13, x = - 3 y + 6

4x-3y=6,5x+2y=19

4 x - 3 y = 6, 5 x + 2 y = 19

7/((3x))+2/y =11, 5/((2x))+3/((4y))=9

\frac{7}{( 3 x )} + \frac{2}{y} = 11, \frac{5}{( 2 x )} + \frac{3}{( 4 y )} = 9
