Let us assign variables.
Let x = egg mcmuffins
Let y = hash brown
Randy had:
2x + y = 750
Jack had
x + y = 450
Using systems of linear equation, we can get the value for x and y by elimination. Subtract the equations.
2x + y = 750
x + y = 450
--------------
x = 300
Get y
x + y = 450
300 + y = 450
y = 150.
So there are 300 calories for McMuffins and 150 calories for hash brown.
Answer:
15 fifths
Step-by-step explanation:
X - the number of pencils
y - the number of pens
She has twice as many pencils as she has pens.

Tom borrows a pen, so she has y-1 pens. Now she has ten less pens than pencils.

Set 2y and y+9 equal to each other:
She has 9 pens.
1. Recall the vertical line equation.
2. Plug in the x that we know.
3. Write down the final equation
