Ответ:
x = -1/11.
Step-by-step explanation:
I am interpreting this as:
(2x+4)/ 3 - (5x-7)/2 = 5
Multiply through by the LCM of 2 and 3 ( that is 6):
2(2x + 4) - 3(5x - 7) = 30
4x - 15x + 8 +21 = 30
-11x = 30 - 21 - 8
-11x = 1
x = -1/11.
Ответ:
This is the equation for a circle. We added plus 6 to the x term to get it to move to the left. And we add minus 5 to the y term to get it to move up 5 units.
