1. Problem Description

The problem asks us to solve the system of two linear equations using the substitution method:
x+2y=10-x + 2y = -10 (1)
6xy=166x - y = 16 (2)

2. Solution Steps

First, we solve the second equation for yy:
6xy=166x - y = 16
y=6x16y = 6x - 16
Next, we substitute this expression for yy into the first equation:
x+2(6x16)=10-x + 2(6x - 16) = -10
x+12x32=10-x + 12x - 32 = -10
11x=2211x = 22
x=2x = 2
Now, we substitute the value of xx back into the equation y=6x16y = 6x - 16 to find yy:
y=6(2)16y = 6(2) - 16
y=1216y = 12 - 16
y=4y = -4
Therefore, the solution is (2,4)(2, -4).

3. Final Answer

The solution is (2,4)(2, -4).
