Answer:

Step-by-step explanation:
We need to find the lateral surface area of the cylinder of radius 6 cm and height of 10 cm.
We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of a cylinder is given by :

So, the lateral surface area of the cylinder is
.
Answer/Step-by-step explanation:
3. By substitution method, let's substitute
for y in the first equation.
Thus,
Solve for x

Add 4 to both sides




Multiply both sides by 3


Divide both sides by 5

Now, substitute 3 for x in the equation.




The solution of the equation is x = 3, y = -2
4. Solving by elimination, let's try to eliminate the x-variable by adding both equation together.


=> 
Divide both sides by -3 to solve for y


Substitute -5 for y in the first equation to find x


Subtract 10 from both sides


Divide both sides by 3


The solution is 
Answer:
-11x +2
Step-by-step explanation:
−(9x + 8) − 2(x − 5)=
-9x -8 -2x +10 =
-11x +2
