I hope this helps you
x^2+4x+3=2x+6
x^2+2x-3 =0
x +3
x -1
(x+3)(x-1)=0
x+3=0 x= -3
x-1=0 x=1
This is a problem for 2 equations and 2 unknown.
so let x be the number of adults in the breakfast
y be the number of children present in the breakfast
so the total people attended is 500, in equation form
x + y = 500
and the total sales made by disney is $ 7355, in equation
17.95x + 12.95y = 7355
so we can solve the equation simultaneously so solve for the values of x and y
so the number of adults at the breakfast x = 176 adults and y = 324 children

Answer:

Step-by-step explanation:
Ir order to find the value of n in the given linear equation:
you have to perform the properties of equalities to obtain an equivalent equation.
You have to perform these properties in each side of the equation.
Applying the subtraction property (which is the subtraction of the same number to each side of the equation):
Adding
to each side:

This way you can obtain the value of n

Solving the subtraction of the fractions and simplifying:
