You add or subtract depending on the equasion. if you give me an example then I can show you but it greatly has to do with the equsion.
10 + 80 = 90 subtract 90 to other numbers to get more equations
Answer:
Evaluate

Step-by-step explanation:
x/(x−4)(x−5)+1/(x−5)
Express

To add or subtract expressions, expand them to make their denominators the same. Least common multiple of x−4 and x−5 is (x−5)(x−4). Multiply

Since
(x−5)(x−4)
x(x−5)(x−5)
and
(x−5)(x−4)
x−4
have the same denominator, add them by adding their numerators.
(x−5)(x−4)
x(x−5)(x−5)+x−4
Do the multiplications in x(x−5)(x−5)+x−4.

Vertical angles are equal
3x - 3 = 6(x - 10)
3x - 3 = 6x - 60

Answer:
744,000
Step-by-step explanation:
3.4 * 10 * 10 * 10 * 10 + 7.1 * 10 * 10 * 10 * 10 *10
3.4 * 10000 + 7.1 * 100000
34000 + 710000
