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

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

x = 147, z = 130 + y

Solution steps

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

Isolate

x

for

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

Substitute

x = 17 - y + z

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

Simplify

[z - y = 130]

Isolate

z

for

z - y = 130 : z = 130 + y

For

x = 17 - y + z

Expressing

x

in terms of

y

x = 17 - y + 130 + y

17 - y + 130 + y = 147

x = 147

The solutions to the system of equations are:

x = 147, z = 130 + y

3 x^{2} - 3 + y^{2} = 0, 2 x y = 0

1 x^{2} + x - 12 = 0, y^{2} - 5 y + 6 = 0

4 x y - 2 x^{2} = - 6, 6 x + 3 y = - 6

f (x) = x^{2} - 5 x + 3, f (x) = - 3

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