Solve for x. 5(x – 10) = 30 – 15x

1 answer:

6 0

You can start by distributing the 5 to everything in the parenthesis.
5x-50=30-15x

Then get rid of your x values from one side, I chose to subtract 5x

-50 = 30 - 20x

Then subtract 30

-80=-20x
/-20
4=x

You can check by plugging your x into the equation to make sure it's right!

If a doesn't equal 0 and the sum of x and 1/a is 0, what does x equal?

Ad libitum [116K]

Answer:

-1/a

Step-by-step explanation:

If a doesn't equal 0 and the sum of x and 1/a is 0, what does x equal?

the sum of x and 1/a is expressed as;

x + 1/a

Equating this to zero

x + 1/a = 0

Find x:

Substract 1/a from bith sides

x + 1/a - 1/a = 0- 1/a

x = -1/a

Hence the value of x is -1/a
