3 x + 10 = 14
subtract 10 from both sides
3 x = 4
multiply each side by 3
x = 12
the "blank" is equal to twelve
the answer is 12 . To confirm this is correct divide 12by 3 and add 10 and you'd get 14:)
The value of the blank in the equation is 12. This was found by first isolating the term with the blank and then multiplying to solve for it. Following the steps of subtraction and multiplication lead us to the solution easily.
