50%x + 2x =-13,25
1/2x + 2x = -13,25
x.( 1/2 + 2) = -13,25
x. 5/2 = -13,25
x = -13,25 : 5/2
x = -5,3
50%x+2x=-13,25
\(\frac{1}{2}\)x+2x=-13,25
\(\frac{5}{2}\)x=-13,25
x=-53/10
Tìm x, biết
a) 3 1/3x+16 3/4= -13,25 b) (2 4/5x-50) :2/3=51 c) |2x-1|=(-4)2 d)x+2/5=-11/15
e) (x-7/18).18/29=-12/29
a) 2/3+1/3:x=3/5
b) 10/3x +67/4=-13,25
c) x+30℅x=-1,3
d) (14/5x -50):2/3=51
e) 2/5+3/5.(3x-3,7)= -53/10
f) 2/3x -3/2x =5/12
Bài 1:Thực hiện phép tính
a, P = 50% . 4/3 . 10 . 7/35 . 0,75
b, Q = 2/3 + 1/3 . ( -4/9 + 5/6 ) : 7/12
Bài 2 : Tìm x biết
10/3 . x + 67/4 = -13,25
13,25:0,5+13,25:0,25+13,25:0,125-13,25:0,25
giúp mình nha
3 1/3 x + 16 3/4 = -13,25
TÌM X :
10/3. x + 67/4 = -13,25
Tìm x, biết
a) 2 2 3 . x + 8 2 3 = 3 1 3
b) 5 , 5. x = 13 15
c) 3 1 3 x + 16 3 4 = − 13 , 25
tìm x biết
1 1/3 . x + 16 3/4 = 13,25
Tìm x
3x+16=-13,25
