Question

66,800 – (x – 1,300) =
25.367

(65,6879-у) + 19,4750 = 48,4646

(x+14,4002000) - 5,2746643) = 16,3838003​

Answer 1

$66,800 - (x-1,300)=25,367\\x-1,300=66,800-25,367\\x-1,300=41,433\\x=41,433+1,300\\x=42,733$

$(65,6879-y)+19,4750=48,4646\\65,6879-y+19,4750=48,4646\\65,6879-48,4646+19,4750=y\\y=17,2233+19,4750\\y=36,6983.$

$(x+14,4002000)-5,2746643=16,3838003\\x+14,4002000=21,6584646\\x=21,6584646-14,4002000\\x=7,2582646.$
