Which properties justify the steps taken to solve the system? {3x−2y=10 4x−3y=14

Alexeev081 [22]

The answer is: Substitution property of equality.

The explanation is shown below:

1. To solve this problem you must apply the proccedure shown below:

2. When you clear the variable x from the first equation, and subtitute it into the second equation, you obtain:

<span>3x−2y=10
x=(10+2y)/3

4x−3y=14
</span>4[(10+2y)/]−3y=14
<span> y=-2

3. When you subsitute y=-2 into the first equation and clear the x, you have:

x=2

URGENT! Can anyone explain how to solve this??

Check the picture below

the triangles are similar, the angles are congruents then

so... just add them up, and divide by 2, or set them as rational
