Question

помогите сделать уравнения срочно

Answer 1

Ответ:

$(x+105)-37=175\\x+105-37=175\\x=175-105+37\\x=107$

$(y+213)-81=405\\y+213-81=405\\y=405-213+81\\y=273$

$250-(175-y)=125\\250-175+y=125\\y=125-250+175\\y=50$

$(200-x)-98=75\\200-x-98=75\\-x=75-200+98\\-x=-27\\x=27$

$1008:(x-15)=72\\x-15=1008:72\\x-15=14\\x=14+15\\x=29$

$9680:(x+314)=16\\x+314=9680:16\\x+314=605\\x=605-314\\x=291$

$1376:(36-y)=86\\36-y=1376:86\\36-y=16\\-y=16=36\\-y=-20\\y=20$

$(y-56)*9=909\\y-56=909:9\\y-56=101\\y=101+56\\y=157$

$(y-48):59=405\\y-48=405*59\\y-48=23 895\\y=23895+48\\y=23 943$

$(y-54)(y-17)(216-6y)=0\\y-54=0 \\y=54\\y-17=0\\y=17\\216-6y=0\\6y=216\\y= 36\\y_{1}=54\\y_{2}=17\\y_{3}= 36$

$(4y-96)(y-23)(81-3y)=0\\4y-96=0\\4y=96\\y=24\\y-23=0\\y=23\\81-3y=0\\3y=81\\y=27\\y_{1}=24\\y_{2} =23\\y_{3} =27$

$(5x-75)(x-19)(76-4x)=0\\5x-75=0\\5x=75\\x=15\\x-19=0\\x=19\\76-4x=0\\4x=76\\x=19\\x_{1}=15\\x_{2}=19$

$(x-7)(3x-9)(13x-39)=0\\x-7=0\\x=7\\3x-9=0\\3x=9\\x=3\\13x-39=0\\13x=39\\x=3\\x_{1}=7\\x_{2}=3$
