If you mean: x+7y = 7 and 2x+y = 8
Then by substitution: x = 49/13 and y = 6/13
If you mean: x+7y = 39 and 3x-2y = 2 Then by substitution: x = 4 and y = 5
-2
x = -2 and y = 1
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
Yes its on the line.

You'd need another equation to sub in

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
By definition: 4x-10 = 5-x 4x+x = 5+10 5x = 15 x = 3 and y = 2
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".
This is not Calculus.y=7(Already solved)substiute y=7 into y=8xtherefore 7 = 8xtherefore x = 7/8
I can give you several sentences.Use that ingredient as a substitution for the one you don't have.He is going in as a substitution for the quarterback.This is a substitution for the real thing.Margarine could be used as a substitution.
In that instance, it means that the lines never touch.
