1) -5 + w/3 = -1
w/3 = -1 + 5
w = 4*3
w = 12
2) 24-3x = -27
-3x = -27 - 24
3x = 51
x = 51/3
x = 17
3) <span>-17 + n/5 = 33
n/5 = 33 + 17
n = 50 * 5
n = 250
4) A) </span><span>3m + 2 = -10
5) </span><span>25 = -75 - 5x
-5x = 25 + 75
x = 100 / -5
x = -20
6) D) </span><span>5 - 7x = 2
Hope this helps!</span>
Add up the same sides of both equations to eliminate <em>x</em> :
(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)
(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5
<em>y</em> = 3
Then
<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8 → <em>x</em> = 14
