I think the mistake is the third step is 3/4x+1/2x then you have to find the common denominator which 4 so next they would have to do 3/4x + 4/4x which is 7/4x
The answer is 83 1/4 if u are adding them all-
Answer:
-3
Step-by-step explanation:
-2.5-0.5=3.0
Given the polynomial equation x^3 -6x = 3x^2 – 8. Which can be simplified into (x^3) -3(x^2) -6x +8 = 0. The roots of the given equation are x = -2, x = 1 and x = 4. The order of equation also represents the number of roots of the equation given. Since the highest exponent is 3, there also 3 roots. So the answer is D. 2 –2, 1, 4
2y-4=y+18
+4 +4
2y=y+24
-y -y
y=24
