Well its easy mean search a video in YouTube
there are two types for systems of question:
The method for elimination
The method for substitution

The elimination only that u have to do is found x or y hat are the sam,e number with different symbols ↓↓like this↓↓

- 7y + 3x = 45
7y + 12x = 33

the y is cancel and... u know the process..
But the method for substitution is different u only need to put the y en the problem and that's it, and when u found the valor of x u can solve for y ↓↓like this↓↓

4x - 2y = 24
y = x - 5

4 (x - 5) = 24
4x - 20 = 24
+20 +20
4x = 44
4x/4 = 44/4
x = 11

Mr.O'Brien is paid $10 per hour for the first 40 hours he works in a week. He is paid 1.5 times that rate for each hour after th

erma4kov [3.2K]

In first 40 hours he earns = 7.30 x 40 = $292
Each hour after his rate = 7.20 x 1.5 = $10.80 per hour
In extra four hours he earns = 10.80 x 4 = $43.20

Total earnings = $292 + $43.20 = $335.20
