Question

If 3 times a certain number is increased by 4 the result is 28. What is the number?

If x is "the number," which of the following equations could be used to solve for the number?

3 x + 4 = 28
3 x = 4 + 28
3( x + 4) = 28

Answer 1

Answer:3x+4=28

Explanation:

the second one would equal 3x=32

And the third one would equal 3x+12=28 which isn’t right either
