If this is a simultaneous equation then:
you should simplify it to get 18+2x=-8x+42+18x
Then simplify again and you get: 18+2x=10x+42
Next if you minus 2x from both sides you get: 18=8x+42
After that you minus 42 from both sides to get: -24=8x
Finally, divide both sides by 8 and you get: -3=x

The length of a rectangle is 3 meter shorter than3 times its width.Find the length and width if the perimeter is 210 meters
Shkiper50 [21]

Answer:

length = 78 m , width = 27 m

Step-by-step explanation:

let w represent width then length l = 3w - 3

the perimeter (P) is calculated as

P = 2l + 2w = 210 , substitute values

2(3w - 3) + 2w = 210 ← distribute parenthesis and simplify left side

6w - 6 + 2w = 210

8w - 6 = 210 ( add 6 to both sides )

8w = 216 ( divide both sides by 8 )

w = 27 and l = 3(27) - 3 = 81 - 3 = 78

Then length = 78 m and width = 27 m
