9x+6y=51,14x-7y=14

Solution

9 x + 6 y = 51, 14 x - 7 y = 14

Solution

x = 3, y = 4

Solution steps

[9 x + 6 y = 51 14 x - 7 y = 14]

Isolate

x

for

9 x + 6 y = 51 : x = \frac{17 - 2 y}{3}

Substitute

x = \frac{17 - 2 y}{3}

[14 \cdot \frac{17 - 2 y}{3} - 7 y = 14]

Simplify

[\frac{238 - 49 y}{3} = 14]

Isolate

y

for

\frac{238 - 49 y}{3} = 14 : y = 4

For

x = \frac{17 - 2 y}{3}

Substitute

y = 4

x = \frac{17 - 2 \cdot 4}{3}

\frac{17 - 2 \cdot 4}{3} = 3

x = 3

The solutions to the system of equations are:

x = 3, y = 4

x+6/y =6,3x-8/y =5

x + \frac{6}{y} = 6, 3 x - \frac{8}{y} = 5

x + y = 10, x = y + 4

4 x - 3 y = 2, x - y = 4

5 x - y = 10, x + 2 y = 2

x+3y+3z=2,3x+9y+3z=3,3x+6y+6z=4

x + 3 y + 3 z = 2, 3 x + 9 y + 3 z = 3, 3 x + 6 y + 6 z = 4
