Answer:
y = 3
Step-by-step explanation:
-7 = -4y + 5
Subtract 5 from both sides to isolate variable y:
-7 - 5 = -4y + 5 - 5
-12 = -4y + 0
-12 = -4y
Divide both sides by -4 to isolate variable y:
-12 ÷ -4 = -4y ÷ -4
(Negative ÷ Negative = Positive)
3 = 1y
3 = y
Check your work:
-7 = -4(3) + 5
Use PEMDAS:
-7 = -12 + 5
-7 = -7
Correct!
Solution: X=6
Detailed explanation:
In this problem we're asked to find "x" or the unknown.
The first step is to subtract 11x from both sides.
![---\mapsto\boldsymbol{-11x+79=13}](https://tex.z-dn.net/?f=---%5Cmapsto%5Cboldsymbol%7B-11x%2B79%3D13%7D)
Next, subtract 79 from both sides.
![---\mapsto\boldsymbol{-11x=-66}](https://tex.z-dn.net/?f=---%5Cmapsto%5Cboldsymbol%7B-11x%3D-66%7D)
To finish this off, divide both sides by -11.
![---\mapsto\boldsymbol{x=6}](https://tex.z-dn.net/?f=---%5Cmapsto%5Cboldsymbol%7Bx%3D6%7D)
Voila! There's our answer!

Answer:
see explanation
Step-by-step explanation:
Since p(x) = x² + 2 , if x ≤ 4
For x = 4 then this is included in the inequality x ≤ 4
whereas x > 4 does not include x = 4 but values greater than 4
Thus to evaluate x = 4 use p(x) = x² + 2
