Answer:
2
Step-by-step explanation:
2x(5+4)=(_x5)+(_x4)
lets start with 2x(5+4)
(5+4)=9
so we are left with 2x9
2x9=18
so now we have 18=(_x5)+(_x4)
lets try 2 for the blank spaces
18=(2x5)+(2x4)
2x5=10
2x4=8
10+8=18
2x(5+4)=(2x5)+(2x4)
It worked! Hope this helps :)

Answer:
x1 = -5
x2 = 3
Step-by-step explanation:
You have the following equation:
(1)
To find the solutions of the equation (1) you first eliminate the denominators of the equation, by multiplying the m.c.m, which is 5x, as follow:
Next, you write the previous equation in the general form ax^2 +bx+c=0, as follow:
Next, you use the quadratic formula to find the solutions:
Then, the solutions for the given equation are x1=-5 and x2=3
