How do you solve x(x+h)=x-h for h?
WITCHER [35]

Answer: H = \frac{-x^{2}+x }{x+1}

Step-by-step explanation:

Step 1: Add h to both sides.

hx+x²+h=−h+x+h

hx+x²+h=x

Step 2: Add -x^2 to both sides.

hx+x²+h+−x²=x+−x²

hx+h=−x²+x

Step 3: Factor out variable h.

h(x+1)=−x²+x

Step 4: Divide both sides by x+1

One number is 28 less than another number. If the sum of the two numbers is 92, find the two numbers.
kiruha [24]

Answer:

The two numbers are <em>32</em> and <em>60</em>.

Step-by-step explanation:

We can create two simultaneous equations to solve this problem using the information given in the question.

Let number 1 = x

Let number 1 = y

x = y - 28 -> ( 1 )

x + y = 92 -> ( 2 )

We can solve simultaneous equations using substitution or elimination. For this question, we will use substitution as it is the easier option.

Substitute ( 1 ) into ( 2 ):

x + y = 92 -> ( 2 )

( y - 28 ) + y = 92

2y - 28 = 92

2y = 120

y = 120 / 2

y = 60 -> ( 3 )

Substitute ( 3 ) into ( 1 ):

x = y - 28 -> ( 1 )

x = ( 60 ) - 28

x = 32

Therefore:

x = 32 , y = 60
