Answer:
D = - 9
Step-by-step explanation:
D - 7 = -18
D - 7 + 7 = -18 + 7
D = -9
Here's how to find the value of x:
<span>9 - 0.75 ( x + 8 ) - 5 = -6.5 find the difference of 9 - 0.75
</span><span>8.25 ( x + 8 ) - 5 = -6.5 add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5 distribute 8.25 to x and 8
8.25x + 66 = -1.5 subtract 66 from both sides
8.25x = -67.5 divide both sides by 8.25
x = 18.18181818...... the value of x is 18 2/11
hope this helps

Answer:
Infinite Solutions
Step-by-step explanation:
If you look at the equation careful you will see this part "-4y+4y". If you see that the variables cancel each other out leaving 2=2. That means that for any value of y, 2=2. Because the variable cancels itself out it doesn't mater what the variable is. So there is an infinite amount of values you can have for "y".
There was an answer already on brainly so here is the answer from Keturah527:
