Question

Solve the equation using inverse operations.check your solutions.

Answer 1

There is equation to solve.However I can give an example using inverse operations and then I will the solution.


28 = 7×
Find the value of x

The opposite operation of multiplication is division.Therefore I can divide 28÷ 7 and 7÷7
.You would cancel out the 7 so you would have x equals to 4.

To check my solution,I would substitute the x by 4 and rewrite the problem as 7 (4) and that is equivalent to 28.So the answer is x=4.

Hope this helps. =)
