Question

Which expressions would complete this equation so that the equation has no solution?

6(4x – 3) – 10x =

Choose exactly two answers that are correct.
A. 14x-15
B. 2(7x-10)
C. 15x-14
D. 2(7x-9)

Answer 1

6(4x – 3) – 10x =

distribute the 6 first

6*4x = 24x
6 * (-3) =-18

24x-18-10x

subtract the 10x from 24x

14x-18



since we know it's 14x-18 we can already see that answer A brings no solution.

because 14x-18=14x-15 you can't find any x that will work. The lines are parallel to each other and will never cross

answer C however is not correct because the lines will cross so you can find exactly 1 solution to it.

so between B and D there's another correct answer

2(7x – 10) = 14x-20



these also never touch just like A


so A and B both have no solutions

the answers are A and B, since we are finding which ones DONT have solutions(:
