x+3y=3,2x-y=1.8

Solution

x + 3 y = 3, 2 x - y = 1.8

Solution

x = 1.2, y = 0.6

Solution steps

[x + 3 y = 3 2 x - y = 1.8]

Isolate

x

for

x + 3 y = 3 : x = 3 - 3 y

Substitute

x = 3 - 3 y

[2 (3 - 3 y) - y = 1.8]

Simplify

[6 - 7 y = 1.8]

Isolate

y

for

6 - 7 y = 1.8 : y = 0.6

For

x = 3 - 3 y

Substitute

y = 0.6

x = 3 - 3 \cdot 0.6

Simplify

x = 1.2

The solutions to the system of equations are:

x = 1.2, y = 0.6

Popular Examples

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

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

x+3y=1,2-2x-4y=24

x + 3 y = 1, 2 - 2 x - 4 y = 24

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

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

5x+4y=20,8x-5y=15

5 x + 4 y = 20, 8 x - 5 y = 15

2 x + y = 1, 4 x + 3 y = 5
