2x-y=0,x+y=15

Solution

2 x - y = 0, x + y = 15

Solution

x = 5, y = 10

Solution steps

[2 x - y = 0 x + y = 15]

Isolate

x

for

2 x - y = 0 : x = \frac{y}{2}

Substitute

x = \frac{y}{2}

[\frac{y}{2} + y = 15]

Simplify

[\frac{3 y}{2} = 15]

Isolate

y

for

\frac{3 y}{2} = 15 : y = 10

For

x = \frac{y}{2}

Substitute

y = 10

x = \frac{10}{2}

\frac{10}{2} = 5

x = 5

The solutions to the system of equations are:

x = 5, y = 10

Popular Examples

8^x=2^{y+1},5^y=25^{x+1}

8^{x} = 2^{y + 1}, 5^{y} = 2 5^{x + 1}

5x_{1}+7x_{2}=3,2x_{1}+4x_{2}=1

5 x_{1} + 7 x_{2} = 3, 2 x_{1} + 4 x_{2} = 1

2y-x=-9,7y-2x=3

2 y - x = - 9, 7 y - 2 x = 3

2u+3v=13,4u+5v=23

2 u + 3 v = 13, 4 u + 5 v = 23

3x+5y=38,3x-y=-4

3 x + 5 y = 38, 3 x - y = - 4
