Answer:
lol
Step-by-step explanation:
First, plug in x=y-8 to y=2x+3
Next, it would be y=2(y-8)+3
Then, you need to distribute: y= 2y-16+3
After that, move 2y to the other side: -y= -13 (notice I also did -16+3)
Finally, divide negatives into both sides: y=13
Now to find x just plug in 13 to either of the equations: 13=2x+3
Then solve: x=5
So the FINAL answer is: (5,13)
Hope this helps!!!!!!!
4 3/8 = (4*8 + 3) / 8 = 35/8
3 1/4 = (4*3 + 1) / 4 = 13/4
