Solve the system of equations: 4x−y=11 6x−2y=13

x=7,y=4.5

Step-by-step explanation:

ok so first you do 4x-y=11,6x-2y=13

then you have to eliminate something

so the easiest one is to multiply the y by -2

the reason why you have to multiply by -2 is because positive cancels out a negative

when you do that you get

x=7

  then you plug in the x into one of the equations. the end was that y=9/2 or

y=4.5

just so the first person can get the points-

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27
