\(460+85x4=\left(y+200\right):4\)
\(460+340=\left(y+200\right):4\)
\(800=\left(y+200\right):4\)
\(y+200=800x4\)
\(y+200=3200\)
\(y=3200-200\)
\(y=3000\)
460 + 85 × 4 = y + 200/4
460 + 340 = y + 50
y + 50 = 800
y = 800 - 50
y = 750

a. x - 4300 - (5250 : 1050 : 250) =4240
x - 4300 - (5 : 250) =4240
x - 4300 - 0,02 =4240
x - 4300 = 4240 + 0,02
x - 4300 =4240,02
x=4240,02+4300
x=854,02
b. 460 + 85 .4 : (x + 200) =4
a. x - 4300 - (5250 : 1050 : 250) = 4240
=> x - 4300 - 1/50 = 4240
x - 4300 = 4240 + 1/50
lk ùi ko lm nữa !! =="

Ta có 460+850x4 = a+200/4
=> 800=a+200/4

ủng hộ nhak
460+85x4=(X+200):4
460+340=(X+200):4
800 =(X+200):4
X+200=800x4
X+200= 3200
X = 3200-200
X = 3000.
K nhé Nguyễn Phương Chi.

3636 : ( 12x - 91 ) = 36
12x - 91 = 3636 :36
12x - 91 = 101
12x = 101 + 91
12x = 192
x = 192 : 12
x = 16
vậy x = 16
460 + 85 . 4 = ( x + 200 ) : 4
460 + 340 = ( x + 200 ) : 4
800 = ( x + 200 ) : 4
( x + 200 ) : 4 = 800
x + 200 = 800 . 4
x + 200 = 3200
x = 3200 - 200
x = 3000
vậy x = 3000
k mk nha bạn
thanks nhìu ^,^
\(3636:\left(12x-91\right)=36\)

460 + 85 *4 = x + 175 / 5 + 30
460 + 340 = x + 35 + 30
800 = x + 65
x = 800 - 65
x = 735
460 + 85 *4 = x + 175 :5 + 30
460 + 340 = x + 35 + 30
