Answer:
The answer is 16x + 7
Step-by-step explanation:
First you want to add all of the like terms.
(8x + 10 + 12x + 7) - (4x+10)
20x + 17 - (4x + 10)
Now you want to subtract all of the like terms
16x + 7
The value of x is drawn from the other angles
(There is no triangle for us to look at) so here is a example
Triangle abc has the values as a=23+x° b=x c=69°
All triangles have a combined value of 180°
Now you would have to add the values together and set it equal to 180
23+x+x+69=180
Combine like terms
(69+23)+(x+x) =180
92+x^2=180
Then subtract 92 from 180
Then you have x^2=88
Then you square root the x^2 to make it just x
Then square root 88 because whatever you did to one side has to be done on the other side
X≈ 9.4

The step which is INCORRECT is no other than the step 4 is incorrect because it shows the incorrect substitution. The step one is correct, the chosen point (2,5) is on the line, same with step 2 where the chosen point (1,3) is also in the chosen line. While step 3 is also correct where the line runs 1 unit rises 2 units such as slope m = 2/1. To make step 4 correct, we should substitute slope in step 3 in the equation below:
(y - y1) = m (x-x1) where m is the slope, in this problem m is 2/1
using point (1,3) and slope m=2/1, we have:
y - 3 = 2 (x - 1)
Thus, step 4 in Talia's solution is incorrect.
