1) x+1/2=-5/3
2) 1/3-x=3/5
4) x-4/3=-7/9
5) x--7/3=5/6
6) x-1/5=9/10
7) x+5/12=3/8
8) x+5/4=7/6
9) x-2/7=1/35
10) x-2/7=-7/10
1) x+1/2=-5/3
2) 1/3-x=3/5
4) x-4/3=-7/9
5) x--7/3=5/6
6) x-1/5=9/10
7) x+5/12=3/8
8) 5/4=7/6
9) x-2/7=1/35
10) x-2/7=-7/10
cả phép tính nữa nha
a,|x-5|=|-7|
b,|x-3|=7-(-2)
giúp mik vs ạ
1) x+1/3=-7/3 4) 2/3+x=7/3
2) 1/8-x=3/8 5) x--7/3=5/3
3) x-4/5=6/5
6) x-1/2=9/2
7) x+5/4=-3/4
8) x+2/7=5/7
9) x-4/3=1/3
10) x+5/2=-7/2
a,x-7=-5
b,128-3.(x+4)=23
d,x-[42+(-28)]=-8
các cậu giúp mik vs ạ!!mình cần đáp án gấp!cảm ơn trước ạ
tìm x
a) \(2\left|x-6\right|+7x-2=\left|x-6\right|+7x\)
b) \(4\left(x-5\right)-7\left(5-x\right)+10\left(5-x\right)=-3\)
giúp mình với!!!
