Answer:
x = -1
Step-by-step explanation:
first you "remove the parentheses" by multiplying the number on the outside of them to everything on the inside. for instance, -2 x 2x = -4x and -2 x -6 = 12 (because whenever you multiply two negatives, it turns into a positive) then, when there is a minus sign in front of parentheses, you change the sign of everything within the parenthesis leaving you with a positive 5 and a negative 3x. so now you have a much simpler equation of -4x + 12 = 8 +5 -3x
next you want to of course add the 5 and the 8 to make it even more simple which would leave you with the equation:
-4x + 12 = 13 - 3x
The next thing you need to do is get the unknown variable on one side of the equation. So you do add 4x do get the x on the right side which would leave you with 12 = 13 - 3x + 4x
So now you can do the same thing to the 13 to try to get it on the left by subtracting 13 from both sides
12 - 13 = -3x + 4x
now you make the equation simple by "combining the like terms" (which is something you'll hear a lot in algebra class)
making you equation -1 = 1x
or just -1 = x because when you multiply something by 1, it's the same.

Step-by-step explanation: Please brainliest if correct!
You need to know and have memorized metric unit conversions. They are easy, you just need to know how many zeros to add.
1 cm = 10 mm
1 m = 1000 mm
1 m = 100 cm
1 km = 1000 m
(1.) 4m + 3cm = 400cm + 3cm = 403cm
(2.) 3km + 8m = 3000m + 8m = 3008m
(3.) 7cm + 9mm = 70mm + 9mm = 79mm
(4.) 1m + 5cm = 100cm + 5cm = 105cm
(5.) 5km + 5m = 5000m + 5m = 5005m
Do you see that to switch 5km to smaller unit meters you just add the zeros on to the end. Because 1km = 1000m ; 5km = 5000m
You try the rest. let me know if you have any questions.
