Solve equation x/6+4=15
RoseWind [281]

x/6+4= 15


Subtract 4 from both sides; 4s cancel each other out

x/6+4-4= 15-4


x/6= 11


multiply both sides by 6 to eliminate fraction (multiply by reciprocal of 1/6)

(x/6)(6)= (11)(6)


x= 66



ANSWER: x= 66


Hope this helps! :)

Ryan has x stamps in his collection if he was 6 times as many stamps as penny, how many stamps does penny have in her collection
Free_Kalibri [48]

The number of stamps with penny in terms of x is \frac{x}{6}

<em><u>Solution:</u></em>

Given that,

Ryan has x stamps in his collection

Number of stamps of Ryan = x stamps

Let the stamps with penny be "a"

Ryan has 6 times as many stamps as penny

Therefore,

Number of stamps in Ryan = 6 times as many stamps as penny

\text{Number of stamps in Ryan } = 6 \times a\\\\x = 6a\\\\a = \frac{x}{6}

Thus number of stamps with penny in terms of x is \frac{x}{6}
