So we have 52 = -2.7x - 3
First Property:
We can add to each side of the equation the same number without changing the equality.
Here, we should add 3 to get 52 + 3 = -2.7x - 3 + 3 => 55 = -2.7
Second Property:
We can multiply each side by the same number without changing the equality.
Here, we should multiply by -1 / 2.7 to get 55 * (-1 / 2.7) = -2.7x*(-1 / 2.7)
=> 55/2.7 =x
x = 550 /2.7
