You’re trying to find the value of y when x=2. You can use either equation to find the value of y. Start with y=−2x+5. Substitute 2 for x in this equation. y=−2x+5 y=4x−7 y = -2x + 5 y = −2 ⋅ + 5

The system of equations tells you that y is equal to −5, so that’s the y-value in our system. To find the value of x in our system, we can substitute −5 for y in the second equation. Do that now. y=−5 x=−6y+3 x = −6( ) + 3

You have x terms on both sides of the equation. What move can you make to get rid of the −24x on the right, so there are only x terms on the left side of the equation? y= 4x−5 x= −6y+20 x = −6(4x−5) + 20 x = −6(4x+−5) + 20 x = −24x + 30 + 20 x = −24x + 50...

Now, add 24x to both sides of the equation to get rid of the −24x on the right, and get all the x terms on the left side of the equation. y= 4x−5 x= −6y+20 x = −6(4x−5) + 20 x = −6(4x+−5) + 20 x = −24x + 30 + 20 x = −24x + 50 + 24x + 24x =

Now, perform the same move to both sides of the equation to find the value of x. y= 4x−5 x= −6y+20 x = −6(4x−5) + 20 x = −6(4x+−5) + 20 x = −24x + 30 + 20 x = −24x + 50 + 24x + 24x 25x = 50 x =

You just found that x = 2. You still need to find the value of y when x = 2. Let's use the first equation, y= 4x−5, since it's already written in terms of y. Start by substituting 2 for x in the first equation. y= 4x−5 x= −6y+20 x = 2 y = 4x−5 y = 4 · −5

Now, evaluate the expression on the right side of the equation to find the value of y. y= 4x−5 x= −6y+20 x = 2 y = 4x−5 y = 4 · 2 − 5 y =
