2x = x+3 2x-x = 3 x = 3

2x=x+3=x=3

x + 3 = 2x 3 = x x cannot be 2

12!

2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3

2x = 4x + 3 -2x = 3 x = -3 / 2

2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3

2x-3 = x+5 2x-x = 8 x = 8

2x+2=x+5 x=3

x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5

2x + 3 = 9 2x = 6 x = 3

Do you need this equation factored or? 2x+3=x+4?

x=3.

the converse of this conditional is true

2x-3=x+2 2x-x=2+3 x=5

x=3

x + 3 + 2x = x + 3 subtract x + 3 to both sides 2x = 0 divide by 2 to both sides x = 0

2x+3 = 9x 3 = 9x-2x = 7x 7x = 3 x = 3/7

x over 4= 2x+3 over 15

x = 3

if it is -X then X=5 if it was minus X the X=10

If: x+9+5x = 21+2x Then: x = 3

if 2x+3=9 then 2x=6 so x=3

X=-1
