3x+8y=19,4x-y=2

Solution

3 x + 8 y = 19, 4 x - y = 2

Solution

x = 1, y = 2

Solution steps

[3 x + 8 y = 19 4 x - y = 2]

Isolate

x

for

3 x + 8 y = 19 : x = \frac{19 - 8 y}{3}

Substitute

x = \frac{19 - 8 y}{3}

[4 \cdot \frac{19 - 8 y}{3} - y = 2]

Simplify

[\frac{76 - 35 y}{3} = 2]

Isolate

y

for

\frac{76 - 35 y}{3} = 2 : y = 2

For

x = \frac{19 - 8 y}{3}

Substitute

y = 2

x = \frac{19 - 8 \cdot 2}{3}

Simplify

x = 1

The solutions to the system of equations are:

x = 1, y = 2

Popular Examples

2x+4y+z=23,6x+2y-z=35,4x-y+2z=19

2 x + 4 y + z = 23, 6 x + 2 y - z = 35, 4 x - y + 2 z = 19

x - 3 y = 5, 7 x - 8 y = 6

5x+3y=35,2x+4y=28

5 x + 3 y = 35, 2 x + 4 y = 28

-x+y=-1,5x-3y=-1

- x + y = - 1, 5 x - 3 y = - 1

x + 3 y = 1, x = 3
