Giúp mik câu này

Tìm x, biết

1/2 + 1/4 x = 3/2

Answer 1

\(\frac{1}{2}+\frac{1}{4}x=\frac{3}{2}\)

\(\frac{1}{4}x=\frac{3}{2}-\frac{1}{2}\)

\(\frac{1}{4}x=1\)

\(x=1:\frac{1}{4}\)

\(x=4\)

Answer 2

\(\frac{1}{2}\)+\(\frac{1}{4}\)x = \(\frac{3}{2}\)

=> \(\frac{1}{4}\)x       = \(\frac{3}{2}\)- \(\frac{1}{2}\)

=> \(\frac{1}{4}\)x       = 1

=> x                = 1 : \(\frac{1}{4}\)

=> x                = 4

Vậy x = 4

Answer 3

Ta có \(\frac{1}{2}+\frac{1}{4}x=\frac{3}{2}\)

\(\Rightarrow\frac{1}{4}x=\frac{3}{2}-\frac{1}{2}\)

\(\Rightarrow\frac{1}{4}x=1\)

\(\Rightarrow x=1.4\)

\(\Rightarrow x=4\)

Answer 4

\(\frac{1}{2}+\frac{1}{4}x=\frac{3}{2}\)

\(\frac{1}{4}x=\frac{3}{2}-\frac{1}{2}\)

\(\frac{1}{4}x=1\)

\(x=1:\frac{1}{4}\)

\(x=4\)
