Algebra help please

Post by sarannie »

Hi, I am struggling terribly with this:simplify 2 (x + 3) = 2 If someone could show me in steps how to work it out I would be very grateful.
Thank you

multiply bracket out
2x+6 = 2

get x to one side

2x =2 - 6

2x = -4

x= -4/2

x = -2

Here is another way :)

Given equation is
2 (x + 3) = 2

Divide both sides by 2
x + 3 = 1

Subtract 3 from both sides
x = 1 - 3 = -2

Cheers!
