Graph the equations to solve the system
y=-x
y=2x+3
click on the correct answer #1 solutions : all numbers on the line #2 no solutions {} #3 one solution: {-1,1} #4 one solution: {0,3}

This system has one solution (-1,1)

Step-by-step explanation:

The attached picture shows the solutions for the system

If we equalize the eq. obtain the following

-x=2x+3

From we obtain that x= -1

Using the first equation y=-x, we obtain that y=1

so (-1,1)

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.
