Answer:

x=-2

Explanation:

To solve this problem, we can use substitution, and combine like terms.

Since y=5x+17, first do:

3(5x+17)

Then, put it in the equation.

4x+3(5x+17)=13

Next, distribute 3.

4x+15x+51=13

Now combine like terms.

19x+51=13

Subtract 51 on both sides.

19x=-38

Finally, divide by 19 on both sides.

x=-2
