let P represent the pencils and N represent the pens
4P + 5N = 2.00
3P + 4N = 1.58
let x represent the cost of the bicycle
The equation is
x + x - 51= 199
Hope i helped... link me if u need nemore help
solve for x and y
solve for S and B
For Problem #1
y = 0.24
for problem #2
dentify the information that is needed to solve the problem.
