Answer:
y = (x-16)/7
Step-by-step explanation:
x - 7y = 16
~Subtract x to both sides
-7y = 16 - x
~Divide -7 to everything
y = (16-x)/7
Best of Luck!
Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)

Answer:
equation
Step-by-step explanation:
Let X is the distance that Anita rode
Let Y is the distance that Cole rode
Cole rode his bike twice as far as Anita, which mean:
Y = 2X
So this situation modeled by an equation
