Bài 1.Tìm x
d,175+(30-x)=200
e,5(x+12)+22=92
f,95-5(x+2)=45
Tìm x, biết
a) 70 - (x - 3) = 45; b) 12 + (5 + x) = 20
c) 130 - (100 + x) = 25; d)175 + (30 - x) = 200
e) (x + 12) + 22 = 92; f) 95 - (x + 2) = 45
tìm X
70-5(x-3)=45
12+(5+x)=20
130-(100+x)=25
175+(30-x)=200
5(x+12)+22=92
Tìm x
92*4-27=(x+350 /x)+315
tìm x
92 . 4 - 27 = ( x + 350 ) : x + 315
Tìm x biết :
92 × 4 -27 = ( x + 350 ) : x + 315
tìm x biết : x+9/98 +x+4/96=94/x+6+92/x+8
