5x-y=3,5x+y=13

Solution

5 x - y = 3, 5 x + y = 13

Solution

x = \frac{8}{5}, y = 5

Solution steps

[5 x - y = 3 5 x + y = 13]

Isolate

x

for

5 x - y = 3 : x = \frac{3 + y}{5}

Substitute

x = \frac{3 + y}{5}

[5 \cdot \frac{3 + y}{5} + y = 13]

Simplify

[3 + 2 y = 13]

Isolate

y

for

3 + 2 y = 13 : y = 5

For

x = \frac{3 + y}{5}

Substitute

y = 5

x = \frac{3 + 5}{5}

Simplify

x = \frac{8}{5}

The solutions to the system of equations are:

x = \frac{8}{5}, y = 5

Popular Examples

y+10x=2y+16,x=5

y + 10 x = 2 y + 16, x = 5

2 x + y = 6, 3 x - y = 18

2 x + y = 6, 3 x - y = 14

a = - 1, 7 b = + 15

10x+51y=617,97x+49y=583

10 x + 51 y = 617, 97 x + 49 y = 583
