Step 1- You Subtract 5 from 17 and get 12 the equation now looks like this
4(x-3)=12
Step 2- You Distrubute by taking the 4 and multiplying it by the x and 3
4(x)= 4x and 4(-3)=-12 The equation now looks like this 4x-12=12
Step 3- You now add 12 to -12 to cancle it out and you add 12 to the 12 behind the = sign and you get 24 you equation now looks like this 4x=24
Step 4- You put 4 under 4 and 4 under 12 as shown 4/4 and 12/4 so you get ride of the 4 so only x is left on that side. 12/4= 3. You are left with x=3 So there is your answer.
