x+y=50,x-6y=-20

Solution

x + y = 50, x - 6 y = - 20

Solution

x = 40, y = 10

Solution steps

[x + y = 50 x - 6 y = - 20]

Isolate

x

for

x + y = 50 : x = 50 - y

Substitute

x = 50 - y

[50 - y - 6 y = - 20]

Simplify

[50 - 7 y = - 20]

Isolate

y

for

50 - 7 y = - 20 : y = 10

For

x = 50 - y

Substitute

y = 10

x = 50 - 10

Simplify

x = 40

The solutions to the system of equations are:

x = 40, y = 10

x - 2 y - 3 z + 5 s - 2 t = 4, 2 z - 6 s + 3 t = 2, 5 t = 10

3x+4y+5=0,y=x+4

3 x + 4 y + 5 = 0, y = x + 4

5 b = 2, a = 1, c = 1

x-3y+z=4,-x+2y-5z=3,5x-13y+13z=8

x - 3 y + z = 4, - x + 2 y - 5 z = 3, 5 x - 13 y + 13 z = 8

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

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