5x-3=27 +3
5x=30 divide by 5
x= 6
Let x = the older student
Let y = the younger student
Let z = the teacher.
x = 2y
z = 5x
z + 5 = 5y Somehow this does not look like its going to be nice.
z = 5y - 5
Since z = 5y - 5 we have
5y - 5 = 5x
y - 1 = x Here's the problem. there is a contradiction. You need to make y bigger, not smaller.
Answer:
Hi there!
Your answer is:
Based off the problem we can tell that the slope is -2/3 and the y intercept is 2. This means we must start our line at the point (0,2). Since slope is in the form rise/run, we know that we must go UP 2 units for every 3 units we go LEFT! We know to go left (As x goes to positive infinity, y goes to negative infinity. ) because the slope is negative!
Hope this helps
