x+y=2,5x-y=5

Solution

x + y = 2, 5 x - y = 5

Solution

x = \frac{7}{6}, y = \frac{5}{6}

Solution steps

[x + y = 2 5 x - y = 5]

Isolate

x

for

x + y = 2 : x = 2 - y

Substitute

x = 2 - y

[5 (2 - y) - y = 5]

Simplify

[10 - 6 y = 5]

Isolate

y

for

10 - 6 y = 5 : y = \frac{5}{6}

For

x = 2 - y

Substitute

y = \frac{5}{6}

x = 2 - \frac{5}{6}

2 - \frac{5}{6} = \frac{7}{6}

x = \frac{7}{6}

The solutions to the system of equations are:

x = \frac{7}{6}, y = \frac{5}{6}

Popular Examples

2x-5y=20,-3(x-y)+y=-2

2 x - 5 y = 20, - 3 (x - y) + y = - 2

x - 3 y = 2, x + y = 6

x+y=14,0x-2y=20

x + y = 14, 0 x - 2 y = 20

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

x + y = 6, 2 x - y = 24
