x+2y=17,x-2y=-3

Solution

x + 2 y = 17, x - 2 y = - 3

Solution

x = 7, y = 5

Solution steps

[x + 2 y = 17 x - 2 y = - 3]

Isolate

x

for

x + 2 y = 17 : x = 17 - 2 y

Substitute

x = 17 - 2 y

[17 - 2 y - 2 y = - 3]

Simplify

[17 - 4 y = - 3]

Isolate

y

for

17 - 4 y = - 3 : y = 5

For

x = 17 - 2 y

Substitute

y = 5

x = 17 - 2 \cdot 5

Simplify

x = 7

The solutions to the system of equations are:

x = 7, y = 5

5x+7y=17,3x-7y=10

5 x + 7 y = 17, 3 x - 7 y = 10

1/3*x-1/3*y=-1/3 ,-1/7*x+1/8*y= 2/7

\frac{1}{3} \cdot x - \frac{1}{3} \cdot y = - \frac{1}{3}, - \frac{1}{7} \cdot x + \frac{1}{8} \cdot y = \frac{2}{7}

x+y-2z=8,2x-y+z=3,3x+y+2z=6

x + y - 2 z = 8, 2 x - y + z = 3, 3 x + y + 2 z = 6
