Question

8*x = 7,8* x + 25

Answer 1

\(8\times x=7,8\times x+25\)

\(8\times x-7,8\times x=25\)

\(\left(8-7,8\right)\times x=25\)

\(0,2\times x=25\)

\(x=25\div0,2\)

\(x=125\)

Answer 2

Lời giải:

\(8x=7,8x+25\)

\(\Rightarrow8x-7,8x=25\)

\(\Rightarrow\dfrac{1}{5}x=25\)

\(\Rightarrow x=25.5\)

\(\Rightarrow x=125\)
