all values stand for 3x+(-5)=19
- 3x-5=19=> 3x=24=> <u>x=8</u>.
Three step requires another step, so it is difficult than two step process.
no, their is no limit to the number of steps it take to solve an equation.
Every number can be described as a sum/difference of two or three numbers.
Answer: In June 2097
Step-by-step explanation:
According to the model, to find how many years t should take for we must solve the equation
. Substracting 21100 from both sides, this equation is equivalent to
.
Using the quadratic formula, the solutions are and
. The solution
can be neglected as the time t is a nonnegative number, therefore
.
The value of t is approximately 85 and a half years and the initial time of this model is the January 1, 2012. Adding 85 years to the initial time gives the date January 2097, and finally adding the remaining half year (six months) we conclude that the date is June 2097.
