X + 9 = 2x - 8
x - 2x = -8 - 9
-x = -17
x = 17
BC = x = 17
We are given an equation with an unknown variable x. We can find the value of x by dividing both sides by 1.76, as this will leave only x on the right hand side of the equation and its value on the left hand side, as shown below:
Thus solving the given equation, we get x =4.16, rounded of to nearest hundredth.
