x+3y=14,3x+2y=21

Solution

x + 3 y = 14, 3 x + 2 y = 21

Solution

x = 5, y = 3

Solution steps

[x + 3 y = 14 3 x + 2 y = 21]

Isolate

x

for

x + 3 y = 14 : x = 14 - 3 y

Substitute

x = 14 - 3 y

[3 (14 - 3 y) + 2 y = 21]

Simplify

[42 - 7 y = 21]

Isolate

y

for

42 - 7 y = 21 : y = 3

For

x = 14 - 3 y

Substitute

y = 3

x = 14 - 3 \cdot 3

Simplify

x = 5

The solutions to the system of equations are:

x = 5, y = 3

Popular Examples

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

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

\frac{4}{x} - y + \frac{1}{x} - y = 3, \frac{2}{x} - y - \frac{3}{x} + y = 5

5x+3y=-1,-3x+4y=-24

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

4/x+3/y =1, 6/x-(16)/y =8

\frac{4}{x} + \frac{3}{y} = 1, \frac{6}{x} - \frac{16}{y} = 8

3x-y=20,6x+3y=60

3 x - y = 20, 6 x + 3 y = 60
