Ответ:
x = -1
Step-by-step explanation:
-2(1 + 2x) = 2(2x + 3)
-2 - 4x = 4x + 6
Subtract 4x to both sides
-2 - 8x = 6
Add 2 to both sides
-8x = 8
Divide both sides by -8 to get x alone
-8x/-8 = 8/-8
x = -1
Hope this helps and pls mark me brainliest if you can:)
Ответ:
Divide both sides by -2
-2(1+2x)=2(2x+3) to 1+2x=-(2x+3)
Then remove the parentheses
1+2x=-2x-3
Then move the variable 2x to the left where the one is.
2x+2x=-3 - 1
Then add both 2x + 2x to 4x
4x=-3 - 1
Subtract -3 -1 which is -4
Now divide both sides by 4
4x=-4 which equals -1
That was a lot but hopefully it made sense :)
