Which of these is an example of a literal equation? A. ax - by = k
B. 12 = 9 + 3x
C. 3x - 4y
O D. 6 + 30 = 62
SUBM

6 + 30 = 62 is literal equation.

B

Explanation:

well if you calculate it,

12 - 9 = 3x

3 = 3x

x = 1

you can find the answer for x but in the other choices you have no inputs for the values therefore all of them are wrong, and D is just wrong because 6 + 30 doesnt equal 62
