x+y=4,+x-y=+2

Solution

x + y = 4, + x - y = + 2

Solution

x = 3, y = 1

Solution steps

[x + y = 4 x - y = + 2]

Isolate

x

for

x + y = 4 : x = 4 - y

Substitute

x = 4 - y

[4 - y - y = + 2]

Simplify

[4 - 2 y = 2]

Isolate

y

for

4 - 2 y = 2 : y = 1

For

x = 4 - y

Substitute

y = 1

x = 4 - 1

Simplify

x = 3

The solutions to the system of equations are:

x = 3, y = 1

2x-4y=36,4x+2y=82

2 x - 4 y = 36, 4 x + 2 y = 82

5a+b=21,2a+3b=24s

5 a + b = 21, 2 a + 3 b = 24 s

(x/5)+y+2=0,(x/3)-y-10=0

(\frac{x}{5}) + y + 2 = 0, (\frac{x}{3}) - y - 10 = 0

a = - 3, b = - 6, c = - 2

x-y=z,y=4z,x+y=81

x - y = z, y = 4 z, x + y = 81
