step 1: 3(x-5)+7=16
step 2: subtract 7 from both sides... (problem should now look like this: 3(x-5)=9)
step 3: use distributive property on the left side... (problem should now look like this: 3x-15=9)
step 4: add 15 to both sides... (problem should now look like this: 3x=24)
step 5: devide both sides by 3... (problem should now look like this: x=8)
step 6: x=8
