How To Solve A System Of Equations: Step-By-Step Guide

What is the solution to the following system of equations?y = 7x + 14y = (1/3)x – 3

( -2.55, -3.85 )

To find the solution to this system of equations, we need to see where the two equations intersect. We can do this by setting the equations equal to each other:

7x + 14 = (1/3)x – 3

We can simplify this equation by getting all the x terms on one side and all the constant terms on the other side:

7x – (1/3)x = -17

Multiplying both sides by 3 to get rid of the fraction, we have:

21x – x = -51

Simplifying this equation, we get:

20x = -51

Dividing both sides by 20, we get the solution for x:

x = -51/20

Now that we know x, we can find y by plugging this value back into one of the original equations. Let’s use the first equation:

y = 7x + 14

Substituting x = -51/20, we get:

y = 7(-51/20) + 14

Simplifying this equation, we get:

y = -153/20

Therefore, the solution to the system of equations is (-51/20, -153/20).
