Question

4.
x-10
= 30
12
Solve for x.

Answer 1

x = 40

Explanation:

x - 10 = 30

=> x = 30 + 10

=> x = 40

Answer 2

40-10=30

Explanation:

x-10=30

we are going to flip the problem which would make it addition so you would do 10+30=X and we can fill in the blank of x equalling 40 because 10+30 is 40
