x+y-z=17,0x+z-y=130x

x + y - z = 17, 0 x + z - y = 130 x

x = - \frac{2210}{129} + 17, z = - \frac{- 129 y + 2210}{129}

Solution steps

[x + y - z = 17 0 \cdot x + z - y = 130 x]

Isolate

x

for

x + y - z = 17 : x = 17 - y + z

Substitute

x = 17 - y + z

[0 \cdot (17 - y + z) + z - y = 130 (17 - y + z)]

Simplify

[z - y = 130 (17 - y + z)]

Isolate

z

for

z - y = 130 (17 - y + z) : z = - \frac{- 129 y + 2210}{129}

For

x = 17 - y + z

Expressing

x

in terms of

y

x = 17 - y - \frac{- 129 y + 2210}{129}

17 - y - \frac{- 129 y + 2210}{129} = - \frac{2210}{129} + 17

x = - \frac{2210}{129} + 17

The solutions to the system of equations are:

x = - \frac{2210}{129} + 17, z = - \frac{- 129 y + 2210}{129}

x - y = 5, x^{2} + y^{2} = 13

2 x + y = 5, x^{2} + y^{2} = 3

2 x - y = 3, x^{2} - x y = - 4

x + 3 y^{2} = 5, 3 x - y = 5 y

(a - b) (a + b) = 16, a + b = 8
