y=x+4
y=3x+0

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=x+4 equation 1

y = 2 + 4

y = 6

therefore the value of x and y are 2 and 6 respectively
