Subtract 3 from both sides so that the equation becomes -2x^2 + 5x - 13 = 0. 
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0 
                                      x = [ -b ± √(b^2 - 4ac) ] / (2a) 
                                      x = [ -5 ± √((5)^2 - 4(-2)(-13)) ] / ( 2(-2) ) 
                                      x = [-5 ± √(25 - (104) ) ] / ( -4 ) 
                                      x = [-5 ± √(-79) ] / ( -4) 
Since √-79 is nonreal, the answer to this question is that there are no real solutions.

Answer:
2
Step-by-step explanation:
Step 1:
- 21w + 9 + 8w = - 5w - 5
Step 2:
- 13w + 9 = - 5w - 5
Step 3:
- 7w + 9 = - 5
Step 4:
- 7w = - 14
Step 5:
14 = 7w
Answer:
w = 2
