1) y = 2x
2) y - x = 5 therefore y = 5 + x
Substituting for y in the first equation gives :-
5 + x = 2x : 5 = x
As y = 2x then y = 2 x 5 = 10
Yes and it works out that x = 3 and y = 4

2x-3y=13
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
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
