X = 18
Steps:
Remove the parenthesis...
4x-6+x = 12+4x
Then cancel out 4x...
-6+x = 12
Then regroup the terms...
x - 6 = 12
Add 6 to both sides...
x = 12 + 6
Then you get...
x = 18
Hope this helped!
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.
