Substituting the equation x equals 2 y plus 3 into the equation y equals short dash 3 x minus 4 will produce the equation _________.
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
Solve using the quadratic formula
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
You'd need another equation to sub in

It can be solved by using the quadratic equation formula.
If: x+y = 8 and 2x-y = 5 Then by adding the equations together: 3x = 13 or x = 13/3 By substitution into the original equations: x = 13/3 and y = 11/3
Solve this system of equation using substitution 2x plus 6y equals 24 and 3x-2x equals 24 ?Improved Answer:2x+6y = 243x-2x = 24 => x =24Substitute the value of x into the top equation to find the value of y:48+6y = 246y = 24-486y = -24y = -4So: x = 24 and y = -4
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.
In that instance, it means that the lines never touch.
y=2x+9 and y=x+6
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
