Question

What is the solution to this awnser 6x+2y=-26

Answer 1

The solution is a pair of numbers ... one for 'x' and one for 'y' ... that
makes the equation a true statement.  There are an infinite number
of solutions.  If you use the equation to draw a graph, then the graph
of it is a straight line without ends, and every point on the line is a
solution to the equation.

Here are a few of them: 

(In each pair, the first number is 'x', the second number is 'y'.)

(-10,17)
(-9, 14)
(-8, 11)
