(1)x+y=5,x-y=-3

Solution

(1) x + y = 5, x - y = - 3

Solution

x = 1, y = 4

Solution steps

[(1) x + y = 5 x - y = - 3]

Isolate

x

for

(1) x + y = 5 : x = 5 - y

Substitute

x = 5 - y

[5 - y - y = - 3]

Simplify

[5 - 2 y = - 3]

Isolate

y

for

5 - 2 y = - 3 : y = 4

For

x = 5 - y

Substitute

y = 4

x = 5 - 4

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 4

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

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

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

2x+3y=8,x-4y=-7

2 x + 3 y = 8, x - 4 y = - 7

3x-2y=14,2x-3y=11

3 x - 2 y = 14, 2 x - 3 y = 11

x=-2+t^2,y=1-2t^2

x = - 2 + t^{2}, y = 1 - 2 t^{2}
