7x-2y=20,x+3y=16

Solution

7 x - 2 y = 20, x + 3 y = 16

Solution

x = 4, y = 4

Solution steps

[7 x - 2 y = 20 x + 3 y = 16]

Isolate

x

for

7 x - 2 y = 20 : x = \frac{20 + 2 y}{7}

Substitute

x = \frac{20 + 2 y}{7}

[\frac{20 + 2 y}{7} + 3 y = 16]

Simplify

[\frac{20 + 23 y}{7} = 16]

Isolate

y

for

\frac{20 + 23 y}{7} = 16 : y = 4

For

x = \frac{20 + 2 y}{7}

Substitute

y = 4

x = \frac{20 + 2 \cdot 4}{7}

\frac{20 + 2 \cdot 4}{7} = 4

x = 4

The solutions to the system of equations are:

x = 4, y = 4

3/2 x+4/3 y=3,5x-y=5

\frac{3}{2} x + \frac{4}{3} y = 3, 5 x - y = 5

2 x + 4 y = 0, x + 3 y = 7

2x+3y-z=15,17x+23y=189,2y-3z=-15

2 x + 3 y - z = 15, 17 x + 23 y = 189, 2 y - 3 z = - 15

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

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

3x+5y=11,2x-y=16

3 x + 5 y = 11, 2 x - y = 16
