Step-by-step explanation:
Hope it's right
X = 34
<span>2+8-x=-24
</span>Add 2 + 8: 10-x=-24
Subtract 10 from each side: -x = -34
Change the signs from each side: x = 34
Answer:
Addition-
(9x+27)
Subraction-
(x-63)
Multiplication-
(20x-810)
Division-
(1.25x-0.4)
Step-by-step explanation:
The answer is:
y= -2.5x + 4
You have to do -2.5 times the x value
Then add 4 and you should get the correct number for each y value.
