Tìm x a)17/6-(x-7/6)=7/4 b)4/3+(1,25-x)=2,25 c)2x-3=x+1/2 d)4x-(2x+1)=3-1/3+x làm hộ mik nhaaaaa

a)17/6-(x-7/6)=7/4

⇔17/6-x+7/6=7/4

⇔4-x=7/4

⇔x=4-7/4=9/4

b)4/3+(1,25-x)=2,25

⇔4/3+1,25-x=2,25

⇔4/3+5/4-x=9/4

⇔4/3+5/4-9/4-x=0

⇔4/3-1-x=0

⇔1/3-x=0

⇔x=1/3

c)2x-3=x+1/2

⇔2x-3-x-1/2=0

⇔x-7/2=0

⇔x=7/2

d)4x-(2x+1)=3-1/3+x

⇔4x-2x-1-3+1/3-x=0

⇔x-11/3=0

⇔x=11/3
