520x=70x+3\times 7
Multiply 2 and 260 to get 520.
520x=70x+21
Multiply 3 and 7 to get 21.
520x-70x=21
Subtract 70x from both sides.
450x=21
Combine 520x and -70x to get 450x.
x=\frac{21}{450}
Divide both sides by 450.
x=\frac{7}{150}
Reduce the fraction \frac{21}{450} to lowest terms by extracting and canceling out 3.
