Answer:

(1,4)

Step-by-step explanation:

y=x+3

y=4x

Substitute the second equation into the first equation

4x = x+3

Subtract x from each side

4x-x = x-x+3

3x =3

Divide each side by 3

3x/3  =3/3

x =1

Now we need to find y

y =4x

y = 4*1

y=4

Y=x+3
Y=4x
4x=x+3
-x. -x
3x=3

3. 3
X= 1
Y=(1)+3=4
Y=4(1)=4
