I need help on these two questions:
-d/6+12=-7
b+1/3=2
-d/6+12=-7
-d/6 = -19
d = 114
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
b+1/3=2
b = 2 - 1/3
b = 1 2/3
Is there a website that can show me a video of it?

Sure! Let's solve the first question step by step:
Step 1: Let's isolate the variable d on one side of the equation. To do this, we'll start by subtracting 12 from both sides of the equation:
d/6 + 12 - 12 = -7 - 12
d/6 = -19
Step 2: Next, to get rid of the fraction (1/6), we'll multiply both sides of the equation by 6:
(d/6) * 6 = -19 * 6
d = -114
So the solution to the first equation is d = -114.
Now, let's move on to the second equation:
Step 1: To isolate the variable b, we will subtract 1/3 from both sides of the equation:
b + 1/3 - 1/3 = 2 - 1/3
b = 2 - 1/3
Step 2: To simplify the right side of the equation, we need to find a common denominator for 2 and 1/3. The common denominator is 3, so we rewrite 2 as 6/3:
b = 6/3 - 1/3
Step 3: Now we can combine like terms on the right side of the equation:
b = (6 - 1)/3
b = 5/3
So the solution to the second equation is b = 5/3.
