a) 175+x*12=10175
x*12=10175-175
x*12=10000

tranquynhnga
175 + 12x = 10175
12x = 10000
x = 10000/12
x = 2500/3
x/26 - 157 =14161
x/26 = 14318
x = 14318 . 26
x = 372268
175 + x * 12 = 10175 x : 26 - 157 = 14161
175 + x = 10175 : 12 x : 26 = 14161 + 157
175 + x = 847,9166... x : 26 = 14318
x = 847,9166... - 175 x = 14318 * 26
x =672,9166... x = 550,6923...
