Question

How do I solve 8 (5 + 7d) = -72

Answer 1

UR SOLVING FOR D SO U DISTRIBUTE 8 TO 5 AND 7D then since you cant add 35 and 56d u subract 35 from both sides then u have
35-35+56d=-72 - 35
56d=-107
then divide 56 into both sides
um nvm i thought i knew i was wrong

Answer 2

To solve for this, we are using the Distributive Property, which allows us to multiply the numbers/variables outside of the parenthesis by the inside numbers/variables.
For example, j(1 + 2) would be j(1) + j(2).
With this information, we can solve or at most simplify the equation.
We have 8(5+7d) = -72.
First, let's use the Distributive Property.
8(5) + 8(7d).
Our products are:
40 + 56d.
Our new equation is:
56d + 40 = -72.
Now we need to get 56d alone.
Subtract 40 from -72, which is basically adding, except the value is different.
-72 -40 = -112
Our equation is now:
56d = 112.
Divide both sides by 56 to solve for d.
56d/56 = d
112/56 = 2
D = 2 is your solution.
I hope this helps!
