Let's use the ratio 3:6 as an example. So 3:6 is the same as 3 over 6, aka 3/6. Divide 3 by 6 and you'd get 0.50. To turn a decimal into a percent, move the decimal to the left 2 times. (If you want to turn a percent into a decimal, you'd move the decimal to the right 2 times.) So then, 0.50 becomes 50%. Hope I helped!!! :-) (You could also multiply the decimal by 100 if you find that quicker/easier)
You can set them equal to each other so -3x+4=4x-10 and then you add 3x and 10 on both sides and get7x=14 and then divided both sides by 7 and get x = 2 and check by plugging in and you get -2 for y on both so solution is x=2
