I’m pretty sure this is right? I’m still learning too :p
Everyday, make her/him learn 3-4 tables. After 3 days, give him/her a 'prize' for it. If that does not work, try teaching him 1 by 1 and memorize it.
The first equation is x = -1
The second and third equations are no solution
The third equation is all rel numbers.
We can tell each one by solving them. In the first one, you get the following.
4 + x = -8x - 5 ----> Add 8x to both sides
4 + 9x = -5 ----> Subtract 4 from both sides
9x = -9 ----> Divide both sides by 9
x = -1
For the middle two, when you attempt to solve, you get untrue statements. This shows there are no solutions. See the example below.
7 + 2x = 2x - 7 ----> Subtract 2x from both sides
7 = -7 (UNTRUE)
And for the last one, each term cancels out, which shows that we have all real solutions.
-3x + 3 = 3( 1 - x) ----> Distribute the 3
-3x + 3 = 3 - 3x ----> Add 3x to both sides
3 = 3 (TRUE)
Mr. Trevor's laptop as he has 400 minutes compared to Mrs Lanes 360 minuted.(6x60=360). So, Mr. Trevor had a total time of 6 hours and 40 minutes.
