Hello,
Let's first set up where x will show the number of high tops. 2x will represent the number of running shoes. Now we can set up and equation:
x+2x=144 Combine like terms
3x=144 Divide both sides by 3
x=48
This shoes us that 48 high tops will be sold and 96 Running shoes will be sold.

"A store owener sells two pairs of running shoes for each pair of high tops" ___ r = 2h

"He plans to order 144 pairs of shoes" ___ r + h = 144

two unknowns (r and h) and two equations

substituting ___ (2h) + h = 144 ___ h = 48

substituting ___ r = 2(48) = 96
