Answer:
There were 186 math textbooks sold and 62 physics textbooks sold.
Given:
- 248 books sold in total
- math textbooks and physics textbooks sold
- math is three times physics
Step-by-step explanation:
[] First, we can set up mathematical equations for this scenario;
- Let <em>m</em> be math textbooks and <em>p</em> be physics textbooks
<em>m</em> = 3<em>p</em>
248 = <em>p</em> + (3<em>p</em>)
248 = 4<em>p</em>
62 = <em>p</em>
[] Now we can solve for the amount of each books sold;
<em>p</em> = 62 books
3 * <em>p</em> = <em>m</em>
3 * 62 = <em>m</em>
<em>m</em> = 186
[] Lastly, we can check to make sure this will work;
186 + 62 = 248 ✓

This is slope-intercept form y=mx+b
when you substitute it, it becomes y=6x-3
