Question

help! Solve for x: the quantity of x plus 20 over 2 = 3x
x = 10

x = 4

x = -14

x = -17

Answer 1

is it (x+20)/2=3x or x+20/2=3x

Answer 2

i got this one

Answer 3

yeah

Answer 4

which one

Answer 5

x + 20/2 = 3x
multiple both sides by 2 to get rid of the 2
2(x+20/2) = 3x(2)
the 2s cancel each other out on the left side
x+20=6x
you want to get the x's on the same side
so subtract x from each side
20=5x
divide both sides by 5 to get x on its own
20/5 = 5x/5
4=x

Answer 6

the second one

Answer 7

lol thanks @TheRealMeeeee

Answer 8

=4

Answer 9

yup anything for u

Answer 10

lol :)

Answer 11

:)

Answer 12

x+20/2=3x
multiply both sides by 2
2(x+20/2)=(3x)2
2x+20=6x
-2x -2x
20=4x
divide both sides by 4
5=x
