Joe weighs 30lbs less than 2wice kens weight
J=2x-30
ken gains 10lbs, then 2gether would weigh 250
(x+10)+J = 250
J=joe's weight.
solve them simultaneously..
hope that helps
Joe weighs 30 lbs less than twice ken's weight. If ken gains 10 pounds then together they would weigh 250 pounds. How much does each of them weigh? let x be ken's weight.
thanks

im confused can you explain a little more cause i need a full equation and im really confused
you need to construct simultaneous equations from the information;
first equation is from; Joe weighs 30lbs less than 2wice kens weight. and x is ken's weight. so twice kens weight is 2x. 30lbs less than twice kens weight is 2x-30. these equals to Joes weight
J=2x-30 (1)
we cannot work with this equation alone because, there are two unknowns J and x. so we need another equation which is obtained from; If ken gains 10 pounds then together they would weigh 250 pounds.
i.e. if ken gains 10lbs (x+10), then together (with J) will equal to 250.
(x+10)+J = 250 (2)
Now we can solve for each weight either by substitution or elimination method..
