Four pencils and five pens cost$2.00. THree pencils and four pens cost $1.58. Find the cost fo a pencil and the cost of a pen.

and then also for this one:

Together, a stakeboard and a bicycle cost $199.00. THe skateboard cost $51.00 less than the bicycle. How much does each cost.

Ok..Number 1

let P represent the pencils and N represent the pens

So

4P + 5N = 2.00

3P + 4N = 1.58

nUMBER 2

let x represent the cost of the bicycle

so

The equation is

x + x - 51= 199

Hope i helped... link me if u need nemore help

x=pencils

y=pen

==============

4x+5y=2.00

3x+4y=1.48

solve for x and y

S+B=199.00

S=B+51

==============

solve for S and B

For Problem #1

I get

x= 0.20

y = 0.24

for problem #2

I get

s=125

b=74
