Answer: b = 8
Step-by-step explanation: To solve for <em>b</em> in this equation, we want to get <em>b</em> by itself on the left side of the equation.
Since 19 is being subtracted from <em>b</em>, to get <em>b</em> by itself,
we need to add 19 to the left side of the equation.
If we add 19 to the left side, we must also add 19 to the
right side in order to keep our equation balanced.
Notice that on the left side, -19 and +19 cancel
each other out so we're simply left with <em>b</em>.
On the right side, -11 + 19 equals 8.
So we have <em>b = 8</em>.
