Answer:
it the 2nd because it has the 2 in it
Step-by-step explanation:
The first two are alike because you have to add 3 to each side for everything to come out even.
8k - 6 = 10k + 6
K= -6
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
8*k-6-(10*k+6)=0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
-2k - 12 = -2 • (k + 6)
Equation at the end of step

:
STEP
2
:
Equations which are never true:
2.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : k+6 = 0
Subtract 6 from both sides of the equation :
Which gives k = -6
