First: combine "like" terms > combine "x" variables > subtract 3.7x from both sides >
22.45x - 3.7x + 1.5 = 3.7x - 3.7x - 2.25
18.75x + 1.5 = -2.25
Sec: subtract 1.5 from both sides (opposite side means opposite sign) >
18.75x + 1.5 - 1.5 = -2.25 - 1.5
18.75x = - 3.75
Third: solve for "x" by isolating it on one side ? divide everything by 18.75 >
18.75x/18.75 = - 3.75/18.75
x = - 0.2

22.45x+1.5=3.7x-2.25
22.45x - 3.7x = -2.25 - 1.5
18.75x = - 3.75
x = -3.75/18.75
Therefore,
x = - 0.2 or - 2/10

22.45x - 3.7x = -2.25 -1.5 (by transpose)
18.75x = - 3.75
x = -3.75 / 18.75 = 0.2
x = 0.2
