Question

To verify that x = 5 is a solution for the equation 8x – 13 = 2x + 17, what is a possible first step?
A.
Multiply 8 by 5.
B.
Subtract 13 from both sides.
C.
Replace x with 5.
D.
Add 17 to both sides.

Answer 1

c

Answer 2

c replace x with 5

Answer 3

b and d dont make sense because you would have to add 13 and subtract 17 plus thats not the first step and a makes sense but c makes the most sense

Answer 4

torch u dont have to add or subtract anything...

Answer 5

c replace x with 5 and if each side equal the other then the solution is correct that x=5 and if one side doesn't equal the other the solution is wrong

Answer 6

if you replace 5 for x you rewrite the equation as 8(5)-13=2(5)+17 and then you solve...

Answer 7

8(5)-13=2(5)+17
40-13=10+17
27=27
the sides of the equation equal each other so the equation is correct x=5 :)

Answer 8

27=27 see correct because 8 x 5 = 40-13 = 27
then 2 x 5 = 10 + 17 + 27
