i need to know this answer to the equation!
i need to know this answer to the equation!
6x - 2 = 2x + 18
(Add 2 to both sides of the =)
6x = 2x + 20
(Subtract 2x from both sides of the =)
4x = 20
(Divide 4 from both sides of the =)
x = 5
(Now plug in 5 as x in the original equation to recheck)
6(5) - 2 = 2(5) +18
30 - 2 = 10 + 18
28 = 28
Use inverse operations to combine like terms on opposite sides of the equals sign; first subtract 2x from each side to eliminate it on the right and leave 4x on the left. Then add 2 to each side to eliminate it on the left and leave 20 on the right.
6x-2=2x+18
turns into:
4x = 20.
If 4 times something is equal to 20..... you can find out what that "something" is by dividing each side by 4..... can you finish this?
