Ariana
y = 5x + 2
Julie
y = 7x
The ys have to be the same so equate the right hand side.
7x = 5x + 2 Subtract 5x from both sides.
7x - 5x = 5x - 5x + 2
2x = 2 Divide by 2
2x/2 = 2/2
x = 1

Answer: equality of a equation
2x-(3y +4)=2x-3y+4
Nothing is wrong with it
x=-5-3
It cannot be more simplified.
58 miles per hour
First you need to divide 80 by 10 to see how many miles she was over the speed limit.
80/10 = 8 miles over the speed limit.
The speed limit was 50, so 50 + 8 = 58 miles.
So Cathy was driving at 58 miles per hour
