Hi there!

Generally, any form is fine, since you always get the same solutions (if you're doing it correctly), but usually, if you encounter something like y = 3x + 2 when the value of y is already given to you, you can just plug the value of y into the other equation and use substitution, but other than that, if the question allows, you should use elimination.

Hope this helps!

Use substitution when either and x or y is given, for instance: x = 2y + 3 or y = 8x - 9.

Use elimination when a number from both equations can cancel each other out, for example:
2x + 3y = 19
-2x + 7y = 12

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 $\frac{x}{6}$

Two dice are rolled, find the probability that the sum is less than 13

Alex777 [14]

100% of the rolls would be less than 13. The highest number on one die is 6, so even if you roll 2 dice the sum of both dice will always be lower than 13.
It's a 1:1 probablility.
