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

Solution

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

Solution

x = 2 - y

Solution steps

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

Isolate

x

for

x + y = 2 : x = 2 - y

Substitute

x = 2 - y

[2 (2 - y) + 2 y = 4]

Simplify

[4 = 4]

The solutions to the system of equations are:

x = 2 - y

Popular Examples

2x+5y=20,3x-5y=30

2 x + 5 y = 20, 3 x - 5 y = 30

5x+4y=7,2x-3y=4

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

3t+4c=65,t+c=18

3 t + 4 c = 65, t + c = 18

x + y = 8, 2 x + y = 10

1/((7x))+1/((6y))=3, 1/((2x))-1/((3y))=5

\frac{1}{( 7 x )} + \frac{1}{( 6 y )} = 3, \frac{1}{( 2 x )} - \frac{1}{( 3 y )} = 5
