4x + -2 = 2x +4

can someone show me how to do this? ? showing all the work then checking the answer but substituting th value back into the original in ”

X=3

Step-by-step explanation:

4x + (-2) = 2x + 4 -- First you need to isolate the x by adding 2 to both sides and subtracting 2x from both sides.

4x + (-2) = 2x + 4

-2x     +2     -2x   +2

2x + 0 = 0 + 6 or 2x = 6 -- Now you divide both sides by 2

                            /2      /2

                            1x = 3  or x=3  -- This is your answer. Now plug 3 back in to check if you are correct.

4(3) + (-2) = 2(3) + 4

12 + (-2) = 6 + 4

10 = 10 -- So, x=3 is correct. Hope I explained it ok for you?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
