smaller ---- x
larger --- 8-x
just translate:
"Four less than five times the smaller is equal to the larger"
----> 5x - 4 = 8-x
take over
since their sum is only 8, it would have been quite easy to do this by simple trial-and-error
The sum of two numbers is eight. Four less than five times the smaller is equal to the larger.
