Alden Paid $197 for 2 similar T-shirts and 3 similar pairs of jeans. Ben paid $236 for 1 such T-shirt and 4 such pairs of jeans. What was the cost of 1 pair of jeans?
Alden 2t + 3j = 197
Ben 1t + 4j = 236 solve for j <===== multiply this equation by -2 to get
-2t -8j - -472 Now add to the first equation....this will eliminate the 't'
-5j = -275
j = 55 dollars
