Answer 2

lets try to solve prob 2)
4x - 7 = 9x + 13 subtract 4x on both side gives
-7 =9x -4x +13 subtract 13 on both sides gives
-7-13 =9x-4x now add or subtract like terms gives
-20 = 5x divide 5 on both sides gives
-20/5=x
x=-4

Answer 3

now this time you can answer prob 1) just understand what process was done on prob 2), also the same as prob 3) the same process you can do... :D
