If a number added to five is divided by the difference of the number and two, the result is three-fourths. Find the number.
alexandr1967 [171]

Answer:

x = - 26

Step-by-step explanation:

Let the number be x.

According to the question,

\frac{x+5}{x-2} = \frac{3}{4}\\

Cross multiplying 4 & 3 gives :-

4(x+5)=3(x-2)

And solving this eqn. gives :-

4(x+5)=3(x-2)\\=> 4x+20=3x-6\\=>4x-3x=-20-6\\=>x=-26

Verification :-

(putting the value of x = -26 )

\frac{x+5}{x-2} \\\\=>\frac{-26+5}{-26-2} \\\\=> \frac{-21}{-28} \\\\=>\frac{21}{28}

Reducing  \frac{21}{28}  by 7 gives  \frac{3}{4} .

What is the y-intercept and x-intercept for the equation -3x - 4 = -5y - 8
BARSIC [14]

Step-by-step explanation:

=> -3x - 4 = -5y - 8

=> 8 - 4 = 3x - 5y

=> 4 = 3x + (-5)y

=> 1 = (3x/4) + (-5y/4)

=> 1 = x/(4/3) + y/(-4/5)

Compare this with x/a + y/b = 1 where a and b are x & y intercepts.

Here,

x intercept = 4/3

y intercept = -4/5
