Reading Jane McGonigal's article, we are presented with the argument that many people have preferred the virtual universe of games over reality, because the experience and expenses of the game are better than those of real life. To reinforce this argument, she shows that real life has been unsatisfactory in many ways and people have used games as an escapism, to participate in a world, where they feel satisfied and happy, where their needs are met. However, McGonigal says that this is something of concern, because it makes us close our eyes to real problems in humanity and uses the escapism of games to ignore them instead of solving them.
Yes, tis correct. (i think)
2 times x(the unknown number to solve for) minus 1 equals 8+7
2x-1=8+7 8+7=15
2x+1=15 Now we have to get x by itself
In order to do that you add 1 from both sides
2x=16 Then you divide 2 from both sides
x=16/2
x=8
