Malik solved this system of equations.

2 x + 4 y = 24. 5 x + y = 15.

As the first step, he decided to solve for x in the first equation because it has a small, even number for the coefficient. Jill told him there was a more efficient way. What reason can Jill give for her statement?
The variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.
The variable x in the second equation has a coefficient of 5 so it will be easy to divide 15 by 5.
The variable y in the first equation is divisible by 2 so it will be the most efficient way to start.
The variable y in the first equation has a larger even number. When dividing by 4, the solution will be a smaller number.

Sagot :

Yes basically 3 and 5 and 2 and divisible yes so ok and + and =

The reason Jill give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution. Hence, option A is the correct statement.

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

System of equations

Given the simultaneous equation;

2x+4y=24

5x+y=15

The best way to solve this kind of system of equation is by the substitution method.

Then To do that in an easy way, we can locate which of the variables in the equations has a coefficient of 1.

From the second equation, we can see that the variable "y' has a coefficient of 1.

Therefore, the reason that Jill can give for her statement is that the variable y in the second equation has a coefficient of one so there will be fewer steps to the solution.

Hence, option A is the correct statement.
