Answer:
x=1/2
Step-by-step explanation:
-5(x - 4) + 6 = 5(3x+4) -4
WE APPLY DISTRIBUTIVE PROPERTY:
-5*x +5*4 + 6 = 5*3x +5*4 -4
-5x + 26 = 15x +20 -4 
26 +4 -20=15x+5x
10=20x
x= 10/20
we have:
x=1/2
 
        
             
        
        
        
Answer:
x - 30
Step-by-step explanation:
3(x - 6) - 4(x + 3)
3x - 18 - 4x - 12
x - 30
 
        
             
        
        
        
Answer:

Answer: -x²+4x-9
Step-by-step explanation:
(g-h)(x) is the same as g(x)-h(x). Since we were given g(x) and h(x), we can subtrac them.
2x-1-(x²-2x+8)       [distribute -1]
2x-1-x²+2x-8         [combine like terms]
-x²+4x-9
Now, we know thhat (g-h)(x)=-x²+4x-9.
 
        
             
        
        
        
Answer:
x = -2
Step-by-step explanation:
1) Rewrite the equation to remove unnecessary parenthesis: x + 5 + 5 - x + x + 2 = 10
2) Remove the opposite variables: 5 + 5 + x + 2 = 10
3) Calculate the sum of the numbers on the lefthand side: 12 + x = 10
4) Subtract 12 from both sides so that x is by itself: x = 10 - 12
5) Solve the equation on the right, and you get your answer: x = -2
