Once ur lines are graphed, the solution is where the lines intersect. So by graphing however many equations u have, the point where they intersect is the solution....unless of course u have parallel lines, then there is no solution. And if ur lines are coincident, the same line on top of each other, then there is infinite solutions.
The answer is twelve fifths
The half life of the substance is 6.92 days.
<h3>What is the Half life ?</h3>
Half life can be defined as the time required to reduce the concentration to half of its initial value.
Here the equation given is

The concentration will reduce to half therefore

so,

ln 0.5 = - 0.1001 * t(1/2)
-0.693 = -.1001 * t(1/2)
t(1/2) = 6.92 days.
Therefore the half life of the substance is 6.92 days.

Step 1: Flip the equation.
44b+11c=a
Step 2: Add -44b to both sides.
44b+11c+−44b=a+−44b
11c=a−44b
Step 3: Divide both sides by 11.
11c11=a−44b11
c=111a−4b
Answer:
c=111a−4b
