To solve the equation 7x = 343, we need to isolate x. We can do this by dividing both sides of the equation by 7.
So, we rewrite the equation:
x = 343 / 7
Now, performing the division:
x = 49
Therefore, the value of x is 49.
This means that if you multiply 7 by 49, you will indeed get 343, confirming that our solution is correct.
