Solve the systems of equations using substitution

-3x+2y=12

x=2y-8

y=3   x=-2

Step-by-step explanation:

-3(2y-8)+2y=12

-6y+24+2y=12

-4y+24=12

-4y=-12

y=3

x=2(3)-8

6-8

x=-2

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
