(K-5/2)^2-25/4 is your answer
Answer:
5
Step-by-step explanation:
//////////////////////////////////////
Multiply the first equation by 2
4x-6y=16
Then add the equations to eliminate x
4x-6y=16
-4x+5y=-10
-y=6
y-=6
Plug the y value in
2x-3(-6)=8
2x+18=8
2x=-10
x=-5
Final answer: (-5,-6)
Answer:
x= - 16
Step-by-step explanation:
substitute y=0 then multuply both sides move the variable to the left and change the sign.
your missing some number to do the process
the first question you add all the sides
