Since b = a, we can plug a into the equation b = b for b on the left-hand side of the equation, and since b = c, we can plug c into the equation for b on the right-hand side of the equation. You can test out of the If we plug b into the left-hand side of a = a, we get _____ = a. Then a − a = 0 (n), and 0 ∈ Z. Even though both sides don’t have their numbers ordered the same way, they both equal 15 and we are therefore able to equate them due to … How about 3 balloons? This gives _____ = _____.
