Y=3x-10 14=2x+3y

Question

What is the ordered pair for the equation

Answer 1

you can uses substitution to solve this system of equations:

 

14 = 2x+3(3x-10)

 

14 = 2x + 9x - 30

44 = 11 x

x = 4

 

now that we have x, can you plug in the value to one of the original equations to find y?

 

Remember that your teacher is asking for an ordered pair - so that needs to include BOTH x and y

Answer 2

Since, y = 3x-10 we will use substitution and sub 3x-10 into the 2nd equation wherever there is a y.

14 = 2x+3(3x-10)

14 = 2x + 9x-30

44 = 11x

4 = x

Y = 3x-10 = 3(4)-10 = 12 -10 = 2

(4,2)
