Y=5x-17 y=x+3 can someone help me with this? thanks

x=5, y=8

Step-by-step explanation:

we can use subsitution to solve this so:

5x-17=x+3 since they bot equal y (y=y)

4x-17=13 subtract x from both sides

4x=20 add 17 to both sides

x=5

then, plug in x to solve for y (either equation) :

y = x+3

y = (5) + 3

y = 8

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
