18 = 10 + 2k

move 10 to the other side

sign changes from +10 to -10

18-10=10-10+2k

18-10= 2k

8= 2k

divide by 2 to get k by itself

8/2= 2k/2

Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k

k=8/2

Answer: k= 4

VikaD [51]

Hey! Your answer for this is

7x^2 + 3x^2 = 10x^2

-2x + 15x = 13x

9 - 4 = 5

Hence, 10x^2 + 13x + 5.

Hope this helps!
