Question

tìm x:

a,\(\left(4:x\right)+6=2\)                    b,6x-3=9

mong mn giups:33

Answer 1

a.

=> 4:x = 2 - 6 = - 4

=> x = -4 : 4 = -1

b.

=> 6x = 9+3=12

=> x = 2

Answer 2

a) \(\dfrac{4}{x}+6=2\\ \Leftrightarrow\dfrac{4}{x}=-4\\ \Leftrightarrow x=-1\)

b) \(6x-3=9\\ \Leftrightarrow6x=12\\ \Leftrightarrow x=2\)

Answer 3

\(a,\left(4:x\right)+6=2\)

\(\left(4:x\right)=2-6\)

\(\left(4:x\right)=-4\)

\(x=4:-4\)

\(x=-1\)

\(b,6x-3=9\)

\(6x=9+3\)

\(6x=12\)

\(x=12:6\)

\(x=2\)
