There was 14 tuna salad sandwiches that were sold. And there was 42 sandwiches that were not tuna salad sandwiches.

Since 25% of 56 is 14, 14 represents how many tuna salad sandwiches that was sold. And you do 56 - 14 to find out how many were not tuna salad sandwiches.

So 14 tuna salad sandwiches sold.

Correct me if I am wrong.

The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"

<h3>System of equation</h3>

System of equation are made of two or more equations with unknowns

Given the system of equation

4x=5-2y

y-2x=7

From equation 2:

y = 7 + 2x

The expression y = 7 + 2x can be substituted into the first equation to find the variable "x"

The equation of the graph y= x^{3}-2x^{2} +3x-4 has no symmetry

The equation of the graph y = x^{3}-2x^{2} +3x-4

Replace y with -y in the given equation

-y = x^{3}-2x^{2} +3x-4

When replacing y with -y gives the different equation. The equation is not symmetric with respect to x axis

Replace x with -x in the given equation

y = (-x)^{3} -2(-x^{2} )-3(-x)-4

y = -x^{3}-2x^{2} +3x-4

When replacing x with -x gives the different equation. The equation is not symmetric with respect to y axis

Replace x with -x and y with -y in the equation

-y = (-x)^{3} -2(-x^{2} )-3(-x)-4

-y =  -x^{3}-2x^{2} +3x-4

When replacing x with -x and y with -y gives the different equation. The equation is not symmetry with respect to origin.

Hence, the equation of the graph y= x^{3}-2x^{2} +3x-4 has no symmetry
