Question

Which of the following systems is equivalent to the given system?

x - y = 2
x + y = -3


2x - 3y = 6 and 2x + y = 6
6x - 3y = 6 and 2x + y = 10
2x - 3y = 6 and 2x + y = -6

Answer 1

First solve for x and y using system of equations for,
x - y = 2
x + y = -3

Then sub that value of x into each pair of equations, the pair that gives you the same y value that you got from the original pair of equations is the equivalent system of equations

Answer 2

Remember a system of equations just shows where two or more equations intersect

Answer 3

do you follow?

Answer 4

yes
