x+y=100,x-y=12

Solution

x + y = 100, x - y = 12

Solution

x = 56, y = 44

Solution steps

[x + y = 100 x - y = 12]

Isolate

x

for

x + y = 100 : x = 100 - y

Substitute

x = 100 - y

[100 - y - y = 12]

Simplify

[100 - 2 y = 12]

Isolate

y

for

100 - 2 y = 12 : y = 44

For

x = 100 - y

Substitute

y = 44

x = 100 - 44

Simplify

x = 56

The solutions to the system of equations are:

x = 56, y = 44

8x-3y=1,3x+2y=16

8 x - 3 y = 1, 3 x + 2 y = 16

2(x+1)+3(y+1)=15,3(x+1)-2(y+1)=3

2 (x + 1) + 3 (y + 1) = 15, 3 (x + 1) - 2 (y + 1) = 3

5x+3y-11z=13,4x-5y+4z=18,9x-2y-7z=25

5 x + 3 y - 11 z = 13, 4 x - 5 y + 4 z = 18, 9 x - 2 y - 7 z = 25

2x+3y=9,6x+9y=18

2 x + 3 y = 9, 6 x + 9 y = 18

x = 2 - y, 2 x - 9 = 3 y
