It is an expression in two variables, x and y.
Thanks to the browser, it is not possible to tell what the inequalities are.
The expression ( y2x + (-3) ) simplifies to ( y2x - 3 ). Here, ( y2x ) represents the term involving the variables ( y ) and ( x ), while ( -3 ) is a constant. Thus, the overall expression combines a variable term and a constant.

If you mean: y = 2x+5 then it is a straight line equation.
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
That is 27 x 9 = 243

Since there is no equality (or inequality) sign in the question, there is no equation or inequality) and therefore nothing which can be solved.
The y value will equal 15, when x = 7
Without any equality signs the given expression can't be considered to be straight line equations.
