Answer:

x/9 + 3 = 7

x = 36

Explanation:

solving an equation with one missing variable

step 1: subtract 3 from both sides of the equation

ex: x/9 + 3 - 3 = 7 - 3 (x/9 = 4)

step 2: multiply both side of the equation by 9

ex: x = 36

step 3: to check your answer input the answer of x from the last problem which was 36 and input it in the original equation

ex: x/9 + 3 = 7 (36/9 + 3 = 7)

4 + 3 = 7

7 = 7 (if both sides of the equation have the same number like 7 = 7 then your answer is true)
