Question

5(а+1)*(-1)=40 срочно

Answer 1

(а+1)*=40*(-1)/5 (а+1)=-8 а=-9

Answer 2

To solve the equation 5(a+1)(-1) = 40, we can start by simplifying the left-hand side:

5(a+1)(-1) = -5(a+1)

Using the distributive property, we can further simplify:

-5(a+1) = -5a - 5

Now we have the equation:

-5a - 5 = 40

To solve for a, we can isolate the variable on one side of the equation. First, we can add 5 to both sides:

-5a - 5 + 5 = 40 + 5

Simplifying:

-5a = 45

Finally, we can solve for a by dividing both sides by -5:

a = -9

Therefore, the solution to the equation 5(a+1)(-1) = 40 is a = -9.
