Question

James used substitution to solve this system of equations. Which could be the result of his first step

Answer 1

Answer:

Option D - $2x+3(x+1.5)=12$

Step-by-step explanation:

Given : James used substitution to solve this system of equations.

Equation 1 - $2x+3y=12$

Equation 2 - $y=x+1.5$

To find : Which could be the result of his first step ?

Solution :          

In substitution method we substitute the value of one variable from a equation and put it into another equation.

We substitute the value of y from equation 2 in equation 1,

Equation 1 - $2x+3y=12$

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

Therefore, the result of his first step is $2x+3(x+1.5)=12$

So, Option D is correct.

Answer 2

Answer: The answer is d=2x+3(x+1.5)=12
