3x+2y=5,2x-y=8

Solution

3 x + 2 y = 5, 2 x - y = 8

Solution

x = 3, y = - 2

Solution steps

[3 x + 2 y = 5 2 x - y = 8]

Isolate

x

for

3 x + 2 y = 5 : x = \frac{5 - 2 y}{3}

Substitute

x = \frac{5 - 2 y}{3}

[2 \cdot \frac{5 - 2 y}{3} - y = 8]

Simplify

[\frac{10 - 7 y}{3} = 8]

Isolate

y

for

\frac{10 - 7 y}{3} = 8 : y = - 2

For

x = \frac{5 - 2 y}{3}

Substitute

y = - 2

x = \frac{5 - 2 ( - 2 )}{3}

\frac{5 - 2 ( - 2 )}{3} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = - 2

Popular Examples

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

x = 4, y = 3

2/((3x))=4,m-5= 2/7

\frac{2}{( 3 x )} = 4, m - 5 = \frac{2}{7}

m + 2 n = 4, 3 m - m = 16

x/2+y/3 =4, x/4+y/6 =2

\frac{x}{2} + \frac{y}{3} = 4, \frac{x}{4} + \frac{y}{6} = 2
