Since i didn’t get an answer last time i’m asking again. answer parts A and B.

X=0 Y=2 (equation has one solution)

Step-by-step explanation: starting with the second equation (y+2x=2) use transposition (or using the inverse operation) to move “2x” do the other side of the equation, this gives you y=-2+2

Now that you have an equation for Y plug it into the first equation (2y-6x=4) it’ll look like this: 2(-2x+2)-6x=4

Use distributive property: -4x+4-6x=4

Combine like terms: -10x+4=4

Use transposition again to move the “4” to the other side: -10x=0

Divide to get “x” by itself: x=0

NOW plug in the value of X into the equation you got for Y (y=-2x+2) it’ll look like this: y=-2(0)+2

Multiply 2 and 0: y=2

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

they charge the same amount at 20 minutes.
