Answer:

x = 8

Step-by-step explanation:

FIrst you move the constant to the right so we add 7 to -11.

Now we have -1/2x = -11+7

Add -11 and 7 which gives us -4

Now we have -1/2x = -4

Multiply both sides by -2

We end up with 8 as X

If I understand correctly, just substitute 15 for C in f = 1.8c + 32, then solve for F
-------------------
f=<span><span>(1.8)(15)</span>+<span>32
</span></span>------------
Simplify
f=<span><span><span>(1.8)</span><span>(15)</span></span>+<span>32
</span></span>f = 27 + 32
f = 59 is your answer
