Amine extracts 2 metric tons of coal in an hour. the mine uses    ton of the extracted coal every hour to generate electricity for the mine and sells the rest. if t is the number of hours spent mining, which expression represents the amount of ore sold? how much ore can the mine sell after extracting ore for 12 hours?

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
