Answer:

1.F

2.E

3.A

4.D

5.B

Step-by-step explanation:

Ax+By=C

1.x+y=3

x+-x+y=3+-x

(x+-x)+y=3+-x

0+y=3+-x

y=-x+3

2.x-3y=9

x-x-3y=9-x

(x-x)-3y=9-x

-3y=9-x

-3y=-x+9

(-3y÷-3)=(-x÷-3)+(9÷-3)

y=3x-3

3.10x-2y=20

10x-10x-2y=20-10x

(10x-10x)-2y=20-10x

-2y=20-10x

-2y=10x-20

(-2y÷-2)=(10x÷-2)-(-20÷-2)

y=5x-10

4.6x=12+2y

(6x-6x)=12-6x+2y

2y=6x+12

(2y÷2)=(6x÷2)+(12÷2)

y=3x-6

5.4x+16-8y=0

move the expression to the right hand-side and change its signs

-8y=-4x-16

change the signs on both signs of the equation

8y=4x+16

divide both sides of the equation by 8

y=1/2x+2

I hope it helps
