<em>They earned $798</em>

<em>The first thing you have to do in order to find your answer is add up the total amount of candy bars sold for the total 3 days. Then once you have that added up, multiply it by 2 (since they were worth 2 dollars each) and you will come up with $798 total.</em>

James used substitution to solve this system of equations which equation could be the result of his first step?

vaieri [72.5K]

Answer: OPTION D.

Step-by-step explanation:

<h3> The compete exercise is: "James used substitution to solve this system of equations. Which could be the result of his first step</h3><h3> $\left \{ {{2x+3y=12} \atop {y=x+1.5}} \right.\\\\\\A.y=2x+3y\\B.y=2x+3y+1.5\\C.2x+3x+1.5=12\\D.2x+3(x+1.5)=12$ "</h3>

Given the sytsem of equations:

$\left \{ {{2x+3y=12} \atop {y=x+1.5}} \right.$

1- Solve for one of the variables from any equation and substitute it into the other equation.

2- Solve for the other variable in order to get its value.

3- Substitute this value back into one of the original equations. and find the value of the other variable.

In this case youu can observe that the second equation is already solved for "y", therefore, in order to use the Substitution Method, the first step is: Substitute the second equation into the first one.

Therefore, the equation that could be the result of James' first step is:

$2x+3y=12\\\\2x+3(x+1.5)=12$
