1. Problem Description

We are given a system of two linear equations with two variables, xx and yy. The system is:
6xy=186x - y = 18
4x+2y=264x + 2y = 26
We need to find the values of xx and yy that satisfy both equations.

2. Solution Steps

We can use the substitution or elimination method to solve this system. Let's use the elimination method.
Multiply the first equation by 2:
2(6xy)=2(18)2(6x - y) = 2(18)
12x2y=3612x - 2y = 36
Now we have the following system of equations:
12x2y=3612x - 2y = 36
4x+2y=264x + 2y = 26
Add the two equations together:
(12x2y)+(4x+2y)=36+26(12x - 2y) + (4x + 2y) = 36 + 26
16x=6216x = 62
x=6216=318x = \frac{62}{16} = \frac{31}{8}
Substitute the value of xx into the first original equation:
6(318)y=186(\frac{31}{8}) - y = 18
1868y=18\frac{186}{8} - y = 18
934y=724\frac{93}{4} - y = \frac{72}{4}
y=934724y = \frac{93}{4} - \frac{72}{4}
y=214y = \frac{21}{4}

3. Final Answer

The solution to the system of equations is x=318x = \frac{31}{8} and y=214y = \frac{21}{4}.
Final Answer: x=318,y=214x = \frac{31}{8}, y = \frac{21}{4}
