Explain how you use substitution to solve a system of linear equations.
Marianna [84]
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.

Three times a first number decreased by a second number
ki77a [65]

Answer:

The two numbers are 3 and 5

Step-by-step explanation:

3X-Y=12\\X + 4Y=17\\

Multiply top equation by 4 to cancel out the Ys

12X - 4Y = 48\\X + 4Y = 17\\\\13X = 65\\X = 5\\

Since X =5, we can plug it into either of the top two equations to find out the value of Y

3(5) - Y = 12\\15 - Y = 12\\Y = 3

To double check

3(5) - 3 \\15 - 3\\12\\\\5 + 4(3) \\5 + 12\\17
