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
First you would do combine like terms but since you have no combine liked terms you would put the numbers in order with the exponents so the 44x^3 then -6x^2 - 8x=0 this is the answer. there is nothing else to do in the problem but to put the numbers in order
Answer:
x + 59 = 0
X= -59
Step-by-step explanation:
For 6: 12, 18, 24, 30, 36
For 9: 18, 27, 36, 45, 54
For 7: 14, 21, 28, 35, 42
The answer is 9.
Hope this helps :)
