Question

8x + 2(x – 7) = 7x + 3x – 14
Solve the equation and write the number of solutions. Show all the steps.

Answer 1

the first step would be to distribute the 2 into the (x-7)

Answer 2

did u get 8x+2x-14=7x+3x-14 ?

Answer 3

yes

Answer 4

great! Next we would combine the like terms so it would like:
10x-14=10x-14
(I just added the 8x and 2x on the first half and added 7x and 3x on the second half)

Answer 5

Since the 10x-14 equals 10x-14 that means all real numbers is the answer.

Answer 6

Does that make sense? :)

Answer 7

so it has infinite solutions

Answer 8

yes
