A phone sells for 137.99. It is now on sale for 1/10 off the original price. Tom has an extra 5% off the sales price. To the nearest dollar, how much less than the original price will tom pay for the phone?

the answer would be  

a.

3: 1

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
