2x+y=12,3x-5y=18

Solution

2 x + y = 12, 3 x - 5 y = 18

Solution

x = 6, y = 0

Solution steps

[2 x + y = 12 3 x - 5 y = 18]

Isolate

x

for

2 x + y = 12 : x = \frac{12 - y}{2}

Substitute

x = \frac{12 - y}{2}

[3 \cdot \frac{12 - y}{2} - 5 y = 18]

Simplify

[\frac{36 - 13 y}{2} = 18]

Isolate

y

for

\frac{36 - 13 y}{2} = 18 : y = 0

For

x = \frac{12 - y}{2}

Substitute

y = 0

x = \frac{12 - 0}{2}

\frac{12 - 0}{2} = 6

x = 6

The solutions to the system of equations are:

x = 6, y = 0

Popular Examples

x+y-z=1,z+x-y=3,z-x+y=7

x + y - z = 1, z + x - y = 3, z - x + y = 7

4x-3y=9,3x-4y=5

4 x - 3 y = 9, 3 x - 4 y = 5

8x-5y+40=7,x-2y=0

8 x - 5 y + 40 = 7, x - 2 y = 0

7/x-(15)/y =9,*(11)/x-8/y =-17

\frac{7}{x} - \frac{15}{y} = 9, \cdot \frac{11}{x} - \frac{8}{y} = - 17

5x-2y=7,4x+3y=-2

5 x - 2 y = 7, 4 x + 3 y = - 2
