2x+y=17,8x-y=83

Solution

2 x + y = 17, 8 x - y = 83

Solution

x = 10, y = - 3

Solution steps

[2 x + y = 17 8 x - y = 83]

Isolate

x

for

2 x + y = 17 : x = \frac{17 - y}{2}

Substitute

x = \frac{17 - y}{2}

[8 \cdot \frac{17 - y}{2} - y = 83]

Simplify

[- 5 y + 68 = 83]

Isolate

y

for

- 5 y + 68 = 83 : y = - 3

For

x = \frac{17 - y}{2}

Substitute

y = - 3

x = \frac{17 - ( - 3 )}{2}

\frac{17 - ( - 3 )}{2} = 10

x = 10

The solutions to the system of equations are:

x = 10, y = - 3

7x-9 y/2-2x+4/2 =-15,5(x-1+y)=25

7 x - 9 \frac{y}{2} - 2 x + \frac{4}{2} = - 15, 5 (x - 1 + y) = 25

2+3y+4z=7,4y=2+5z,3z-2x+6=0

2 + 3 y + 4 z = 7, 4 y = 2 + 5 z, 3 z - 2 x + 6 = 0

2x+3y=5,3x+2y=7,3x-2y=1

2 x + 3 y = 5, 3 x + 2 y = 7, 3 x - 2 y = 1

2x+3y-z=18,x-2y+4z=21,3x-y-3z=3

2 x + 3 y - z = 18, x - 2 y + 4 z = 21, 3 x - y - 3 z = 3

2x+4y=7,3x-6y=10

2 x + 4 y = 7, 3 x - 6 y = 10
