Hey there!
a + 2 = t
a + 2 = -4
SUBTRACT 2 to BOTH SIDES
a + 2 - 2 = -4 + 2
CANCEL out: 2 - 2 because it gives you 0
KEEP: -4 + 2 because that helps get the result of the a-value
a = -4 + 2
-4 + 2 = a
SIMPLIFY ABOVE & YOU HAVE THE VALUE OF THE A
a = -6
Therefore, your answer is: a = -6
Good luck on your assignment and enjoy your day!
