2f +4f +2 -3
combine the like terms to get 6f-1
so yes they are equivalent
2f+4f+2-3 at f=3 would also be 17
The value of the variable x in the equation –x + 8 + 3x = x – 6 is - 14.
<h3>How to find variable in an equation?</h3>
The variables of an equation can be found as follows:
–x + 8 + 3x = x – 6
The variable in the equation is x.
Therefore,
–x + 8 + 3x = x – 6
combine like terms on the left side
-x + 3x + 8 = x - 6
2x + 8 = x - 6
subtract x form both sides of the equation
2x - x + 8 = - 6
x + 8 = -6
subtract 8 from both sides
x = -6 - 8
x = - 14

66 x .25 = 16.5 Have a great day.
Answer:
2080
Step-by-step explanation:
The solution to these equations might best be found using Cramer's Rule. It tells you ...
x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400
This is years after 1990, so the year the incomes become the same is predicted to be ...
1990 +90.4 = 2080.4
The median incomes will be the same in the year 2080.
28°
a triangle = 180°
180°-140°= 40°
180°-68°= 112°
180°-112°-40°= 28°
