Answer 3

Let's solve the equation step by step:

1. Start with the equation × + 5 = 9.
2. To isolate ×, we need to move 5 to the other side of the equation by subtracting 5 from both sides: × + 5 - 5 = 9 - 5 × = 4

So, × = 4.

Now, let's solve the equation 30 + а = 70:

1. Start with the equation 30 + а = 70.
2. To isolate а, we need to move 30 to the other side of the equation by subtracting 30 from both sides: 30 + а - 30 = 70 - 30 а = 40

So, а = 40.

Now you have the values for both × and а:

× = 4 а = 40
