The number of pretzels and hot dog sales will be 33 and 48.
<h3>What is the solution to the equation?</h3>
The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Let x be the number of pretzels and y be the number of hot dogs.
Joanie runs the concession stand for the school's baseball games.
At each game, the best-selling items are pretzels and hot dogs.
Pretzels are $3 each, and hot dogs are $2 each.
Today she sold 15 more hot dogs than pretzels and made $195 in total sales. Then the equations will be
y = x + 15 ....1
3x +2y = 195 ...2
From equations 1 and 2, then we have
3x + 2(x + 15) = 195
3x + 2x + 30 = 195
5x = 165
x = 33
Then the value of y will be
y = 33 + 15
y = 48
Then the number of pretzels and hot dog sales will be 33 and 48.

Answer:
x=64
Step-by-step explanation:
* change equivalent to to = *
now we have x² - 16x + x = (x-8)²
step 1 simplify both sides
(x)²=x²
-8x*2=16x
8=64
-16x + x = 15x
now we have x² -15x = x² - 16x + 64
step 2 subtract x² from each side
x² -x² = 0
x² - x² cancels out
now we have -15x = -16x + 64
step 3 add 16x to each side
-15x + 16x = x
-16x + 16x cancels out
we're left with x = 64
