<span>For the following system, use the second equation to make a substitution for y in the first equation.
2x + y = 6
y = 3x + 4
</span>substitute y = 3x + 4 into 2x + y = 6
2x + y = 6
2x +( 3x + 4) = 6
answer is <span>2x + (3x + 4) = 6 (last choice(</span>
2x + y + 3x + 4 = 6 is the correct equation :)

Let w be the width;and 2w-3 be the length. Then:
w(2w-3)=27
2w²-3w-27=0
(2w-9)(w+3)=0
w=9/2 or -3
The width is 9/2 ft, the length is 6
