2x+3y=20,x-2y=3

Solution

2 x + 3 y = 20, x - 2 y = 3

Solution

x = 7, y = 2

Solution steps

[2 x + 3 y = 20 x - 2 y = 3]

Isolate

x

for

2 x + 3 y = 20 : x = \frac{20 - 3 y}{2}

Substitute

x = \frac{20 - 3 y}{2}

[\frac{20 - 3 y}{2} - 2 y = 3]

Simplify

[\frac{20 - 7 y}{2} = 3]

Isolate

y

for

\frac{20 - 7 y}{2} = 3 : y = 2

For

x = \frac{20 - 3 y}{2}

Substitute

y = 2

x = \frac{20 - 3 \cdot 2}{2}

\frac{20 - 3 \cdot 2}{2} = 7

x = 7

The solutions to the system of equations are:

x = 7, y = 2

x+4y-8z=-8,4x+8y-z=76,8x-y-4z=110

x + 4 y - 8 z = - 8, 4 x + 8 y - z = 76, 8 x - y - 4 z = 110

3x+5y=2,9x-y=-1

3 x + 5 y = 2, 9 x - y = - 1

2x+6y=22,5x-2y=4

2 x + 6 y = 22, 5 x - 2 y = 4

x + y = 3, 2 x + y = 2

(12)/x+5/y =-13/2 ,(18)/x+7/y =-19/2

\frac{12}{x} + \frac{5}{y} = - \frac{13}{2}, \frac{18}{x} + \frac{7}{y} = - \frac{19}{2}
