It is four. So two and two you add them together to be four. Good job. Your learning :)
This is false... you can get an easy example: (-2) + (10) = 10 - 2 = 8
Isolate for each variable.
1. z= 6 - 10
z= -4
2. y= 48/8
y=6
3. q= 1+12
q= 13
4. 18 x 2= a
36= a
5. r= 7 x 3
r= 21
I think you can try the rest :)
The app photo math is really awesome,
