Depending on the type of story given, you need to determine the value of y where x is 0 on the graph or by substitution of the equation.
By substitution
You can find a chord substitution chart PDF online on music theory websites, music forums, or by searching on search engines like Google.
a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16

There are many places one might go to find a home value calculator. The official Chase website offers this type of calculator in addition to other resources.
You use substitution when you can solve for one variable in terms of the others. By substituting, you remove one variable from the equation, which can then be solved. Once you solve for one variable, you can use substitution to find the other.

12x - 5 = 30Add 5 to each side:12x = 35Divide each side by 12:x = 35/12=======================y = 2x - 6Substitute the value of 'x' :y = 2(35/12) - 6Clear parentheses:y = 35/6 - 6y = 35/6 - 36/6y = -1/6
