Answer:

x = 4

Step-by-step explanation:

An equilateral triangle means that all three sides are equal. All triangles have an inner angle measure of 180 degrees. Divide 180 by 3 to find out a singular angle's measure. You end up with : 10x + 20 = 60. In order to isolate the 10x, subtract 20 from both sides. This gives you 10x = 40. Thus, x = 4.

I need to find how many solutions does the system have. ​
REY [17]
From what I got there is one real solution :)

Rearrange the second equation to give y=2-2x, substitute into the first equation to give you a value for x and then using that you can work out y for the exact coordinates of intersection :)

Also they are both straight line graphs so they will either have one or no solutions

Hope this helped :)
