-2x+5y=13,16x+3y=25

Solution

- 2 x + 5 y = 13, 16 x + 3 y = 25

Solution

x = 1, y = 3

Solution steps

[- 2 x + 5 y = 13 16 x + 3 y = 25]

Isolate

x

for

- 2 x + 5 y = 13 : x = - \frac{13 - 5 y}{2}

Substitute

x = - \frac{13 - 5 y}{2}

[16 (- \frac{13 - 5 y}{2}) + 3 y = 25]

Simplify

[43 y - 104 = 25]

Isolate

y

for

43 y - 104 = 25 : y = 3

For

x = - \frac{13 - 5 y}{2}

Substitute

y = 3

x = - \frac{13 - 5 \cdot 3}{2}

- \frac{13 - 5 \cdot 3}{2} = 1

x = 1

The solutions to the system of equations are:

x = 1, y = 3

Popular Examples

x + 2 y = 1, - 3 x - y = 2

5 x - y = 6, x + 3 y = 10

x+6y=27,7x-3y=9

x + 6 y = 27, 7 x - 3 y = 9

3x-5y=20,6x-10y=40

3 x - 5 y = 20, 6 x - 10 y = 40

3x-4y=-6,2x+4y=16

3 x - 4 y = - 6, 2 x + 4 y = 16
