James has a total of 66 dollars in his piggy bank. he only has one dollar bills and two dollar bills in his piggy bank. if there are a total of 49 bills in james's piggy bank, how many one dollar bills does he have?

17

Step-by-step explanation: 66 - 49 = 17

He has 32 1 dollar bills and 17 2 dollar bills I THINK

32 + 17 = 49 and 32 + 17(2) = 66

(17 is wrong I can confirm)

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
