I'm assuminng you want to find x and y
eliminate
hmm
eliminate y's
3 times 2=6
multiply first equation by 2 and 2nd by 3 and add
16x-6y=-32
<u>15x+6y=-123 +</u>
31x+0y=155
31x=155
divide both sides by 31
x=5
sub back
5x+2y=-41
5(5)+2y=-41
25+2y=-41
minus 25 both sides
2y=-66
divide by 2
y=-33
(x,y)
(5,-33)

Answer:
The degrees of angle x is 180 degrees.
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of x.
3 + 12 (y-4) = 40
*Use distribution*
3 + 12y - 48 = 40
*combine like terms*
-45 + 12y = 40
* what you do to one side of the equation you have to do to the other side
-45 +12y = 40
+45 +45
-----------------------
12y = 85
*now you divide to isolate variable*
85
------- = 7
12
Y =7
