<span>1st</span></span><span> formula 2n + 3m = 280
</span><span><span>
</span><span>2nd</span></span><span> formula 2n + 5m = 320
</span><span><span>
</span><span>rearrange 1st</span> formula to equal n:</span>
<span><span>2n = -3m + 280
</span>
</span><span>n = -3/2

</span><span>rearrange 2nd</span> formula to equal n:</span>
<span><span>2n = -5m + 320

</span><span>n = -5/2m + 160

so now you have
</span>-3/2m + 140 = -5/2m + 160 </span>
<span><span>Rearrange to become:
</span>
</span><span><span>-3/2m + 5/2m = 160 - 140

</span>
<span>Now place 20 into the very 1st</span><span><span> equation in place

Draw a rectangle and label the right side as L-3 and the bottom side as L.
Area is L x W...in this case L(L-3) = 40.....we get
L^2 - 3L = 40 (subtract 40 from each side we get...)
L^2 - 3L - 40 = 0 (factor this out to get the L and W)
8 and 5
3x-4= 6x-19 » -4+19 = 6x-3x » 15 = 3x » 15/3 = x » x = 5
Given
Erin Lytle's gross pay is $26,300
She takes a married exemption of $4,000
state income tax rate is 5.5%
Find out she pay in state income tax
To proof
Gross pay = $26,300
married exemption = $4,000
Let the she pay in state income tax = x
5.5 % written in the simpler form
= 
= 0 .055
than the equation becomes
x = 0.055 ( 26300 - 4000)
x = 0.055× 22300
x = $1226.5
Erin Lytle pay in state income tax is $ 1226.5
Hence proved
