Answer:
x = -7
Step-by-step explanation:
4x-9 = 7x+12
Add 9 to both sides
4x = 7x + 21
Subtract 7x from both sides to further isolate the variable
-3x = 21
Divide both sides by -3
x = -7
Plug the value in to check your work:
4(-7) - 9 ? 7(-7) +12
-28 - 9 ? -49 + 12
-37 ? -37
-37 = -37
If this is talking about the Pythagorean theorem then it would be 5,12,13 becuase because the equation for the triangle is
2 2 2
a + b = c
2 2 2
5 + 12. = 13

Answer:
Step-by-step explanation:
Let the Price of TV set be x.
The price of computer = x - 5200
x + x - 5200 = 105200
2x = 105200 + 5200
2x = 110400
x = 110400/2
x = Rs. 55200
Price of TV set = Rs. 55200
Price of computer set = 55200 - 5200 = Rs. 50000
