Answer:
x=-1
Step-by-step explanation:
4x-16=-20
Get x to one side by subtracting it.
-16=-20-4x
Add the 20 on both sides.
-16+20=-4x
Simplify
4=-4x
4/-4=-4x/-4
-1=x
x=-1
To find x just change the <span>> to a =
</span><span>3x-7=5
add 7
3x=12
then divide by 3
x=4

Answer: y = 6
Step-by-step explanation:
A square's area can be done by using s^2, where s is y in this case. Because there are 5 squares, the area of the figure is 5y^2. Because the area is also 180cm, 5y^2=180.
Then divide both sides of the equation by 5 to get y^2 = 36. Then square root both sides of the equation to get y = 6.
