Q(-3,-3)
R(3,2)
S(5,2)
T(5,-4)
Cuando has simplificado la ecuación lo mas posible y las expresiones de los dos lados quedan iguales, hay soluciones infinitas. Pero, dado que lo has simplificado y son diferentes, no hay solución.
1.) 7x = 12 + 7x - 12
=> 7x = 7x => infinita solución
2.) x - 11 = 11 + x
=> x = 22 + x => no solución
3.) 2(4x - 6) = 8(x + 2)
=> 8x - 12 = 8x + 16 => 8x = 8x + 28 => no solución
4.) 2x - 9 = 2x - 9
=> infinita solución
5.) 8 + 4x = 4x + 10
=> 4x = 4x - 2 => no solución
Answer: 
Step-by-step explanation:
The first step is to make the division of the fractions 
and
. To do this, you can flip the fraction over and multiply the numerators and the denominators of the fractions. Then:
Reduce the fraction 
:
Now you can make the subtraction: in this case the Least Common Denominator (LCD) will be the multiplication of the denominators. Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:
8 21/100 is your answer! :)
A) 2 and 7
B) 2 and 6
C)6 and 3
