The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

Step-by-step explanation:

Given equations are:

There are three methods to solve simultaneous equations

We will use the elimination method as the coefficients of x in both equations are already same

Subtracting equation 2 from equation 1

Putting y = 3 in equation 2

Hence,

The solution for given system of equations is: x = 6 and y = 3

Or

(6,3)

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
