Answer: x=4 and BC=20 STEPS: Set the equation for AC and DF equal to each other then solve for x. 2x+7=5x-5 Eliminate the -5 by adding it to both sides. 2x+12=5x Move the x to one side by subtracting 2x from both sides. 12=3x Isolate the x by dividing both sides by 3 4=x EF=5x which means BC=5x 5(4)= 20 So BC= 20
