Sandals and flip-flops on sale at the store! Janet purchased 3 pairs of sandals and 1 pair of flip-flops for $23.50, while Michael purchased 2 pairs of flip-flops and 4 pairs of sandals for $33. Find the price of each pair of sandals and each pair of flip-flops.

1 sandal= $7

1 flip flop =$2.5

Step-by-step explanation:

say one sandal costs x and one flip flop costs y

3 x+y=23.50

4x+2y=33

solve using simultaneous equationsto find the values of x and y

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
