If you mean: y = x^2+4x+3 and y = 2x+6 Then the solution is: x = 1 or x = -3
Without a second independent equation, it's not a 'system' yet.
If you mean: y = 2x+5 then it is a straight line equation.

The y value will equal 15, when x = 7
If you mean: y = x^2+4x+3 and y = 2x+6 Then the solution is: x = 1 or x = -3
It is an expression in two variables, x and y.
Without a second independent equation, it's not a 'system' yet.
If you mean: y = 2x+5 then it is a straight line equation.
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2). Neither y2x nor x 2y5 is an equation.

If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
Without any equality signs the given expressions can't be considered to be equations so therefore there are no solutions.
Since there is no equality (or inequality) sign in the question, there is no equation or inequality) and therefore nothing which can be solved.
