Answer:
18x+21
Step-by-step explanation:
First multiply each equation by 2 since there is 2 sides for both the length and width.
2(2x+3) 2(7x+9)
4x+3 14x+18
Then combine like terms
4x+14x 3+18
18x 21
Answer:
y= -3
Step-by-step explanation:
<u>Multiply all terms by the same value to eliminate fraction denominators:</u>
2/y +3 = 3/3y + 9
(3y+9) (y+3) (2/y+3) = (3y +9) (3/3y+9)
<u>Simplify:</u>
6
+
1
8
=
3
+
9
<u>Subtract 18 from both sides of the equation:</u>
6y +18 =3y +9
6y+18 -18 =3y +9 -18
<u>Simplify Again: </u>
6y +3y-9
<u>Subtract 3y from both sides of the equation:</u>
6y =3y -9
6y-3y = 3y -9 -3y
<u>Answer:</u>
y= -3
