2x+8=2(3x-4)
i need getting the answer

-2x+8=6x-8 (multiply the outer 3 with the values in the brackets)
8+8=6x+2x (put the x-s in one side and the numbers in the other, changing the sides also results into changing the signs - becomes + and vice verse)
16=8x (do the addition)
16/8=8/8x (divide both sides by the number of x)
2=x (do the division the answer you’ll get is that the value of x is 2)

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
