Answer:
20 inches and 5 inches
Step-by-step explanation:
Let the diameter of the largest and the smallest pizza be Y and X respectively.
Then,
Y+X = 25 ........................... Equation 1
Y-X = 15 ............................ Equation 2
Solve equation 1 and equation 2 simultaneously.
Add equation 1 and equation 2
Y+Y = +X+(-X)+25+15
2Y = 40
Y = 40/2
Y = 20 inches.
Also,
Substitute the value of Y into equation 1
20+X=25
X = 25-20
X = 5 inches.
Hence the diameter of the largest and the smallest pizzas = 20 inches and 5 inches

Answer:
Solving for x gives x=7
Step-by-step explanation:
First lets rewrite our equation clear, which from the question reads as :
Eqn(1).
This is a case of an equation with one variable <em>(i.e. one uknown)</em> denoted as .
The question is asking as to solve this equation and obtain the value of .
To do so we start by rewriting and simplifying the equation as follow:
which is the same as
Here we have a fraction on the left hand side reading as and an integer on the right hand side as . Thus we move the denominator of the fraction, in this case to the right hand side where we multiply it with , to eliminate our fraction and solve for as follow:
(Note how we transferd from the left hand side to the right hand side, the sign changed from <em>negative </em>to <em>positive). </em>
Hello!
2y(4-x)=x/2
<span>[plug in 2 for x] </span>
<span>2y(4-2)=2/2 </span>
<span>[4-2 is 2, 2/2 is 1] </span>
<span>2y(2)=1 </span>
<span>[divide both sides by 2] </span>
<span>2y=1/2 </span>
<span>[divide by 2 again] </span>
<span>y=1/4
</span>
====>So As Result As We See, y = 1/4.<====
Hope this Helps! Have A WONDERFUL Rest Of Your Day! :)
