start with \[12.5\times 2x=15(x+2)\] and solve for \(x\)
OpenStudy (astrophysics):
Ah, so this one requires a ratio to, like your last question, thanks @misty1212

Nope, you may have messed up somewhere, \[(12.5)(2x)=15x+30\]
OpenStudy (anonymous):
25x=15x+30
OpenStudy (astrophysics):
\[25x=15x+30\]
OpenStudy (astrophysics):
Yes
