Each load will take 3 gallons. Therefore, we can express the amount of water that will be used for x loads using the equation w=3x, where w is how much water you use and x is equal to how many loads there are. We can set up the equation:
w=(3*4)+(3*
)
From there, we can solve
w=12+(3*)
simplifies to
w=12+
w= 12
:)
w=(3*4)+(3*
From there, we can solve
w=12+(3*
simplifies to
w=12+
w= 12

Answer:
x = 1
y = -3
Step-by-step explanation:
We have the value of <em>x</em> in terms of <em>y</em> already, so our first step will be to plug in <em>y + 4</em> for <em>x</em> in the first equation. This gives us:
From here, we can just solve for <em>y</em>:
And now that we know <em>y = -3</em>, we can solve for <em>x</em> using the second equation:
Lastly, we should just double check our answers using the first equation to see if they work:
It does!
