\[-4x+16=116\] this is what you have right? @carsonce
OpenStudy (anonymous):
yep
OpenStudy (photon336):
Subtract 16 from both sides
-4x+16 = 116-16
-16
This is what we get.
-4x = 100
-4 -4
now divide both sides by -4
x = 100/-4 = -25
x = -25

@carsonce please let me know if there's something you don't get
OpenStudy (photon336):
we can check this too watch
OpenStudy (photon336):
-4(-25) = 100 + 16 = 116
116 = 116
this is how we check
OpenStudy (anonymous):
Ohhh that makes sense
OpenStudy (photon336):

How would you do this?
The perimeter of a rectangular photo is 72 cm. The length is twice the width. What are the length and width of the photo?
OpenStudy (anonymous):
@Photon336
OpenStudy (photon336):
let's translate this the length is TWICE the width
So the length is 2x and the width is x
Does this make sense?
