Solve for x: 4 over x plus 4 over quantity x squared minus 9 equals 3 over quantity x minus 3?

Answers

4/x + 4/(x²-9) = 3/(x - 3) 
4 / x + 4 / [( x - 3) ( x + 3 )] = 3 / ( x - 3 )  / * x ( x - 3 ) ( x + 3 )
Restrictions : x ≠ 0,  x ≠ - 3 ,  x ≠ 3;
4 ( x + 3 ) ( x - 3 ) + 4 x = 3 x ( x + 3 )
4 ( x² - 9 ) + 4 x = 3 x² + 9 x
4 x² - 36 + 4 x - 3 x² - 9 x = 0
x² - 5 x - 36 = 0
x² - 9 x + 4 x - 36 = 0
x ( x - 9 ) + 4 ( x - 9 ) = 0
( x - 9 ) ( x + 4 ) = 0
x - 9 = 0,  or : x + 4 = 0
Answer:
x = 9,  x = - 4

3g=6g-7
Any help appreciated

Answers

Subtract 6g from both sides.
-3g = -7
Divide both sites with 3.
-g = -7/3
Multiply both sides with -1
g = 7/3

How do you factor, 45c + 10d?

Answers

We can't factor out a c or d, since we don't know c in terms of d, or vise versa.  We thus can only factor out an integer.  We see that both numbers are divisible by 5, so we factor out a 5, for a result of 5(9c+2d).  9 and 2 do not have any common factors other than 1, so we have factored fully.  Thus, the answer is 5(9c+2d).

You drive 1400 miles in 3.5 days. You drive an equal number of miles each day. How many miles do you drive each day.
