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
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
x = -2 and y = 1
You'd need another equation to sub in

Yes its on the line.

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.
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
Accuracy.
