Substitute your x and y into the equations x=1 y=3
Y = x - 2
3 = 1 - 2. Is not a true statement and is your answer

Solve for m pls? I'd seriously appreciate it!
Vilka [71]

Answer:

m=-1

Step-by-step explanation:

Start by multiplying both sides by 2, this will get rid of the fraction on the left side and will result in the equation 12m+6=2m-4

Then, subtract 2m from both sides, which leaves the equation as 10m+6=-4

Then, subtract 6 from both sides, this results with the equation 10m=-10

Finally, divide both sides by 10, this will result in m=-1

Answer:

45

Step-by step

What do we already know about the equation?

We know that they EACH bought a hockey puck($17) and 2 shirts

Half of 214 is 107. So they had to have spent 107 separately

So we make the equation and let s represent shirts

2s + 17 = 107

    - 17            -17

2s= 90.    DIVIDE by 2

s = 45
