Question

Solve for x: 7x + 15 = 38 (5 points)
Select one:
a. 23/7
b. 53/7
c. 23
d. 53

Answer 1

since you have 7x + 15, you can subtract 15 from both sides to isolate 7x

what do you get after this step?

Answer 2

?

Answer 3

7x + 15 - 15 = ?

Answer 4

7x?

Answer 5

oh wait

Answer 6

good, and since we subtracted 15 from the left side we must also subtract 15 from the right side

7x = 38 - 15 = 23

Answer 7

yes 7x

Answer 8

so if 7x = 23

what does x = ?

Answer 9

16?

Answer 10

good attempt but not quite

since 7 is being multiplied to x, we would do the opposite of multiplying by 7, which is dividing by 7

so divide both sides by 7, what do you get?

Answer 11

so divide 23 by 7 and 32 by 7?

Answer 12

hm, I'm not sure where you're getting 32 from

you have 7x = 23

dividing both sides by 7 gives us

7x/7 = 23/7

x = 23/7 = your solution

Answer 13

i meant 23 not 32 whoops haha
