Find solution to the system of linear equations. 3x1 + 6x2 = 2 , 9x1 + 12x2 = 1

x₁ = -1

x₂ = 5/6

Step-by-step explanation:

The equations of the given linear system are:

Multiply the first equation by -2 and add it to the second one to solve for x₁:

Since we already know the value of x₁, simply replace it in the first equation  to solve for x₂:

The solution for the system is x₁ = -1 and x₂ = 5/6

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
