Case I : 1.28 = (x - 170)/11
1.28 = (x - 170)/11
1.28 * 11 = x - 170
x - 170 = 14.08
x = 14.08 + 170
x = 184.08
====
Case II : 1.28 = x - (170/11)
1.28 = x - (170/11)
1.28+ (170/11) = x
x = (32/25) + (170/11)
x = (352/275) + (4250/275)
x = 4602/275
1.28 = (x - 170)/11
1.28 * 11 = x - 170
x - 170 = 14.08
x = 14.08 + 170
x = 184.08
====
Case II : 1.28 = x - (170/11)
1.28 = x - (170/11)
1.28+ (170/11) = x
x = (32/25) + (170/11)
x = (352/275) + (4250/275)
x = 4602/275

is this 1.28 = x - (170/11) or 1.28 = (x - 170)/11 ?
1.28 = x - 170/11
1.28 + 170/11 = x
1.28 + 15.454545... = 16.73454545... = x
1.28 = (x - 170)/11
14.08 = x - 170
184.08 = x
1.28 = x - 170/11
1.28 + 170/11 = x
1.28 + 15.454545... = 16.73454545... = x
1.28 = (x - 170)/11
14.08 = x - 170
184.08 = x

x = 1.28 + 170/11

x = 1.28/-15.45
x = -0.0828237
x = -0.0828237

1.28 = 128/100 = 32/25, so you must solve
32/25 = x - 170/11, add 170/11 to both sides
32/25 + 170/11 = x, combine the two fractions
4602/275 = x
32/25 = x - 170/11, add 170/11 to both sides
32/25 + 170/11 = x, combine the two fractions
4602/275 = x

1.28 = x - 170 /11
x
= 1.28 + 15.4545454....
= 16.7345...
x
= 1.28 + 15.4545454....
= 16.7345...
