Answer:
x= 2
y = 6
Step-by-step explanation:
to solve this system of equation using substitution method,
let
y=x+4............................................................. equation 1
y=3x+0............................................................. equation 1
substitute equation1 into equation 2
we have,
x + 4 = 3x + 0
combine the like terms
4-0 = 3x -x
4 = 2x
divide both sides by the coefficient of x which is 2
4/2 = 2x/2
x = 2
put x = 2 in equation 1
y = 2 + 4
therefore the value of x and y are 2 and 6 respectively
since both equal y, you can set them equal to each other
subtract x on both sides
divide by 2 on both sides
2 = x
