Distribute 2/5 and 3/5 into the ():
2/5(a+b)+3/5(a+c)

2/5 a+ 2/5 b+3/5 a+ 3/5 c

combine the like terms:
2/5 a+3/5 a= 5/5 a --> 1a --> a

new simplified equation:
a+2/5 b+3/5 c

What are the solutions to the equation x - 7/x = 6

bearhunter [10]

The answer is C that is X=7 and X=-1

multiple x through the given equation to get rid of a fraction. It will be

${x}^{2} - 7 = 6x$

After that bring 6X to the LHS of the equation

so that it will look like the general equation that is

${x}^{2} - 6x - 7 = 0$

Use the quadratic formula (or any other approach to find the values of x

You will arrive at

$x = 7. - 1$
