Mr. pham wrote the equation below on the board.

18 - 7x=-20.5

what is the value of x?

x=5.5

Step-by-step explanation:

We can solve this equation by using the various properties and PEMDAS.

First, we would want to subtract 18 on both sides, to even out the equation.

The result is -7x=-38.5

Now we can isolate the x by dividing both sides by -7.

-38/-7=5.5

Thus, x=5.5

Hope this helps!

step-by-step explanation:

step 1: simplify both sides of the equation.

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
