Question

16 - 13(b + 5) + 17 = 4b + 5(6-b) +10

Answer 1

Ответ: -6

Пошаговое объяснение:

16 - 13(b + 5) + 17 = 4b + 5(6-b) +10

16-13b-65+17=4b+30-5b+10

-13b-4b+5b=30+10-16+65-17

-12b=72

b=72:(-12)

b=-6

Answer 2

Let's solve the equation step by step:

16 - 13(b + 5) + 17 = 4b + 5(6 - b) + 10

First, let's simplify both sides of the equation by performing the operations within parentheses:

16 - 13b - 13(5) + 17 = 4b + 5(6) - 5b + 10

Next, let's simplify further by performing the multiplications:

16 - 13b - 65 + 17 = 4b + 30 - 5b + 10

Combine like terms on each side of the equation:

-13b - 32 = -b + 40

Now, let's isolate the variable terms on one side and the constant terms on the other side:

-13b + b = 40 + 32

Simplifying further:

-12b = 72

Divide both sides of the equation by -12:

b = 72 / -12

Simplifying the division:

b = -6

Therefore, the value of b that satisfies the equation is -6.
