Solve each equation for xx. for each step, describe the operation used to convert the equation. how do you know that the initial equation and the final equation have the same solution set?
a. 1/5[10−5(x−2)]=1/10(x+1)
b. x(5+x)=x²+3x+1
c. 2x(x²−2)+7x=9x+2x³

a. x=1.8?

Step-by-step explanation:

im not really sure but i need help also. Im sorry but i just thought to say something.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
