So just your normal equation.
We need to isolate x alone.
First lets write out our equation
3 +7x = 12
Lets do this step by step.
first subtract 3 from both sides.
3 + 7x = 12
-3 = -3 it cancels out on the left side and we solve on the right side.
*************
7x = 9
second we divide both sides by 7
7x = 9
÷7 = 7 we got the x alone and we just write 9/7 as our answer.
x = 9/7
Or as a decimal.
9/7 could be <span>1.28571428571429
</span>
Either will work.
x = 9/7
or
x = <span>1.28571428571429
</span>
Have a nice day. :)
Answer:
Solve for X-B(5,0.85), for x = 3.*25*
delete my question if it's wrong
Ok so we can state that for 5 days he gets 80 dollats meaning that for 1 day he should get 16 dollars i.e
80 dollars -> 5 days
80/5 = 16
1 day -> 16 dollars
Now find the amount of money <span>earned for 14 days by multiplying by 14.
16*14 = 224
14 day -> 224 dollars.
Hope this helps :).
