Answer :
Luis and Baca would be the same weight after 60 weeks of weightlifting.
What is a linear Equation?
A linear equation is one in which the highest power of the variable is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation.
To create an equation that Luis and Baca can use to determine how long it will take for them to be the same weight:
Let the time taken by Luis and Baca to be of the same weight be x weeks,
Given:
Initial weight of Luis = 194 pounds
Initial weight of Baca = 218 pounds
Then,
Weight gained by Luis in x weeks = 0.6x pounds
Weight gained by Baca in x weeks = 0.2x pounds
Total weight of Luis after x weeks = (194 + 0.6x ) pounds
Total weight of Baca after x weeks = (218 + 0.2x) pounds
For Luis and Baca to be of the same weight,
Total weight of Luis after x weeks = Total weight of Baca after x weeks
Therefore, we equate the total weight gained by Luis and Baca after x weeks to determine the value of x
⇒ 194 + 0.6x = 218 + 0.2x
⇒ 0.6x - 0.2x =218 - 194
⇒ 0.4x = 24
⇒ x = 60
Hence, Luis and Baca would be the same weight after 60 weeks of weightlifting.
