User: In the solution of the equation 5 - 3x = 2x + 9, 3x is added to the equation first. Which of the following should be done next?

Weegy: (3x-2) squared is 9x^2 - 12x + 4.

User: What is the solution set of the following equation? -8x + x + 15 = -7x + 12

Weegy: INPUT THE NUMBERS like for f(2) you would put 2(2)^2-7(2)+3= the answer. thank you for using weegy

User: Solve for x. 3(3x - 1) + 2(3 - x) = 0

Weegy: 3(3x - 1) + 2(3 - x) = 0 ; 9x - 3 + 6 - 2x = 0 ; 7x +3 = 0 ; 7x = -3 ; x = -3/7. The answer is B. x = -3/7

User: Solve for B. R = x(A + B)

Weegy: 1/a+b+x=1/a+1/b+1/x =>(1/a+b+x)-1/x=1/a+1/b Taking (a+b+x)x as LCM, =>x-(a+b+x)/(a+b+x)x=b+a/ab =>-(a+b)/x2+ax+bx=a+b Cancelling (a+b) from both sides we get, => -1/x2+ax+bx=1/ab => x2+ax+bx= -ab =>x2+ax+bx+ab=0 => x(x+a)+b(x+a)=0 =>x+b=0 [ or x+a=0 =>x=-b or x=-a ]

User: The first side of a triangle measures 5 in. less than the second side, the third side is 3 in. more than the first side, and the perimeter is 17 in. How long is the third side? If s represents the length of the second side, which of the following represents the length of the third side?

Weegy: s-2 is the length of the third side. s=8 so the length of the third side is 6.
