1. what is the solution to the system of equations?
3x-6y= -12
x-2y= -8
(a) use the substitution method to justify that the given system of equations has no solution.
(b) what do you know about the two lines in this system of equations

I have the same question but I only need to do b

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
