\(5\times\left(4+6x\right)=290\)
\(\Rightarrow4+6x=290:5\)
\(\Rightarrow4+6x=58\)
\(\Rightarrow6x=58-4\)
\(\Rightarrow6x=54\)
\(\Rightarrow x=54:6\)
\(\Rightarrow x=9\)
5x.(4+6x)=290
5x.10x = 290
50x = 290
x = 290 : 50
x = \(\dfrac{29}{5}\)

RÚT GON
5X+3-|6X-4|
Tìm x biết 5x.(2-3.x)=4-6x
rút gọn biểu thức
5x+3-|6x-4|
f)(2.x-8).(4.x+16)=0
g)5x.(6x-12)=0
h)7.(9-x)(12-6x)=0
6x=3x+1-5x+6x-5x+4x-9x+7x
a)-12+x=5x-20
b)7x-4=20-3x
c)5x-7=-21-2x
d)x+15=7-6x
e)17-x=7-6x
làm ơn giải giùm với,mình sẽ like cho
a) 4(x+3)-(2x-12)=x-(-11+4)
b) -(4x-13)+(5x-4)= -3-(-15+7)
c) (5x-3)-(-2x+4)=6x-12
d) (15x+20)-(9x-3)=5x-(-12)
e) (7x+14)+(3x-8)= -(-9x+3)
giúp mình nha.................
tìm x biết:
|x2 - 5x+4| = |x2 - 6x +5 |
