2x+y=7,3x+2y=12

Solution

2 x + y = 7, 3 x + 2 y = 12

Solution

x = 2, y = 3

Solution steps

[2 x + y = 7 3 x + 2 y = 12]

Isolate

x

for

2 x + y = 7 : x = \frac{7 - y}{2}

Substitute

x = \frac{7 - y}{2}

[3 \cdot \frac{7 - y}{2} + 2 y = 12]

Simplify

[\frac{21 + y}{2} = 12]

Isolate

y

for

\frac{21 + y}{2} = 12 : y = 3

For

x = \frac{7 - y}{2}

Substitute

y = 3

x = \frac{7 - 3}{2}

\frac{7 - 3}{2} = 2

x = 2

The solutions to the system of equations are:

x = 2, y = 3

Popular Examples

9/x+(10)/y =-11, 7/x-(15)/y =-4

\frac{9}{x} + \frac{10}{y} = - 11, \frac{7}{x} - \frac{15}{y} = - 4

4x+2y=9,8x+2y=14

4 x + 2 y = 9, 8 x + 2 y = 14

x= 17/11 ,z= 4/121

x = \frac{17}{11}, z = \frac{4}{121}

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

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

y+1=2,(x-1)ey-1=x+1

y + 1 = 2, (x - 1) ey - 1 = x + 1
