Let's denote Brad's current weight as x
According to the problem, Sean weighs 10 lbs more than twice Brad's weight, so Sean's current weight is2x + 10
If Brad gains 10 lbs, his weight will bex + 10
Together, Brad and Sean weigh 230 lbs, so we have the equation:
x+10+(2x+10)=230
Solving forx
3x+20=230
3x=210
x=\frac{210}{3}
x=70\text{ lbs}
So, Brad's current weight is approximately 70 lbs.
Plugging this back into the expression for Sean's weight:
2(70\overline{})+10=2\times70\overline{}+10=150\text{ lbs}
Therefore, Brad currently weighs approximately 73.3 lbs and Sean currently weighs approximately 156.6 lbs.
\boxed{\text{Brad: 70 lbs, Sean: 150 lbs}}
