In this question, you have to isolate <em>x</em>.
First, use the distributive property.

Now that you have distributed, subtract the constants.
Given that 24 hours is one full day, we can deduce that 2400 hours is 100 days. One full cycle from that time is equivalent to that time therefore, 2400 hours after 5pm is 5pm.

"<span>The difference of six times a number and 7 is -49"...
In number and variables, this would be:
</span>

<span>
Add
7 to both sides.
</span>

<span>Simplify.
</span>

Divide both sides by
6.

Simplify.

Hope this helps.

Sin74 = Cos16
cause 16 + 74 = 90
Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :
Sin(30) = Cos(60)
and also
Tan(30) = Cot(60)
