Answer:
the solution to the equation -2(b + 5) = 4 is b = -7.
Explanation:
To solve for b in the equation -2(b + 5) = 4, we can start by simplifying the equation using the distributive property. We multiply -2 by both the expressions inside the parentheses.
-2(b + 5) = 4
-2b - 10 = 4
Now, let's isolate the variable b.
First, we can add 10 to both sides of the equation to get rid of the -10 on the left side.
-2b - 10 + 10 = 4 + 10
-2b = 14
To solve for b, we need to get rid of the coefficient -2. We can do this by dividing both sides of the equation by -2.
(-2b) / -2 = 14 / -2
b = -7
