x+89=74+x
x+89-x=74+x-x
89 not=74
so no solution
y/54*54=(2y-59)*54
y=108y-3186
108y-y=3186
107y=3186
y=29.77570093
x+89-x=74+x-x
89 not=74
so no solution
y/54*54=(2y-59)*54
y=108y-3186
108y-y=3186
107y=3186
y=29.77570093

x+89=74+x
x-x = 74 -89
0 = -14
x= no solution
y/54 = 2y -59
y/54- 108y/54 = -59
-107y/54 = -59
y = -59 x -54/107
y= 3186/107
x-x = 74 -89
0 = -14
x= no solution
y/54 = 2y -59
y/54- 108y/54 = -59
-107y/54 = -59
y = -59 x -54/107
y= 3186/107
