First you would do 5-2. That would give you 3(x-1)=12 Next, 3 would be distributed into x-1 That would give you 3x-3=12 After that, you add 3 on both sides of the equal sign. That would give you 3x=15 Finally, divide 3 on both sides and your final answer is: x=5 If you do a Check, 12 will equal 12. Hope this helps!!!
