Linear equations: 5 +2(2x-3)+8x = -5x +2. and . 5 -2(2x-3)+8x = -5x +2

Plz show your work.

hello,I'll edit the process and say step by step.

result= 28x-30= -70x²+73x-18 = -5x+2

Sorry, it was a little long process. I could not explain them all. I said the result directly.And I am Turkish, sorry if there is a problem with my pronunciation.But remember, you will do it according to the distribution in the parenthesis.

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
