Answer:

x=3, y = 15

Step-by-step explanation:

We can solve using the substitution method by substituting 3x+6 for y...

x+3x+6=18

Combine like terms

4x+6=18

4x=12

x=3

Now we need to find y. We can plug 3 in for x to solve for y...

y=3(3)+6

y=9+6

y=15

(x,y)=(3,15)

Answer:

x = 6

<u><em>Sorry if this answer is not correct, if it is or is not, please tell me in the comments!</em></u>

Step-by-step explanation:

All of the angles add up to 180 degrees (since it is a triangle), so

(11x - 3) + (7x + 5) + (13x - 8) = 180

Then, combine the like terms.

31x - 6 = 180

Now, out goal is to separate the x from everything. To do that, we need to add 6 to 180.

31x = 186

Then divide by 31.

x = 6

(Feel free to replace x with 6 back in the previous equation to double check it!)
