The x-variable will be eliminated when adding the system of equations since -2x + 2x = 0
The sum of the system of equations is 4y = -12, since 11y + -7y is -4 and -13 + 1 = -12
y = -3, since when you solve for y in 4y = -12 you get -3 (divide both sides by -4)
The first statement is true because 2x + -2x = 0
3rd statement is also true.
Statement 5 is also true.
