a,-/x-3/+16=4
b,3-(17-x)=289-(36+289)
c,25-(x+5)=415-(15-415)
d,34+(21-x)=(3747-30)-3746
a.484+x=(-632)+(-548)
b.(-x)+(-62)+(-46)=-14
c.25+(x-5)=-415-(15-415)
tìm x
a, |x+3| -12 = |-5|
b, 25 - (x-5) = 415 x (15 - 415 )
tìm x :
a) 3 - ( 17 - x ) = 289 - ( 36 + 289 )
b) 25 - ( x + 5) = - 415 - ( 15 - 415 )
c) 3 ( x - 1) - ( x - 5 ) = 8
bài 1: tìm x, biết
a, 3-(17-x)=289-(36+289)
b,25-(x+5)=(-415)-(15-415)
c,34+(21-x)=(3747-30) -3746
tim so nguyen x, biet
a, 3-[17-x] = 289-[36+289]
b,25-[x+5]=-415-[15-415]
tìm số nguyên x,biết
a/ 3-(17-x)=289-(36+289)
b/ 25-(x+5)=-415-(15-415)
c/ 34+(21-x)=(3747-30)-3746
25+(x-5)=-415-(15-415)
25+(x-5)=-415-(15-415)
