x+y=3,2x+y=2

Solution

x + y = 3, 2 x + y = 2

Solution

x = - 1, y = 4

Solution steps

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

Isolate

x

for

x + y = 3 : x = 3 - y

Substitute

x = 3 - y

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

Simplify

[6 - y = 2]

Isolate

y

for

6 - y = 2 : y = 4

For

x = 3 - y

Substitute

y = 4

x = 3 - 4

Simplify

x = - 1

The solutions to the system of equations are:

x = - 1, y = 4

(12)/x+5/y =-13/2 ,(18)/x+7/y =-19/2

\frac{12}{x} + \frac{5}{y} = - \frac{13}{2}, \frac{18}{x} + \frac{7}{y} = - \frac{19}{2}

x + y = 3, 2 x + y = 3

3 a + 5 b = 2, 6 a + 5 b = 22

x+3y=-8,4x-5y=2

x + 3 y = - 8, 4 x - 5 y = 2
