Answer:
The equation is 4x + 5 = 2x + 6
Step-by-step explanation:
The solution is 
means x =
Let us put the coefficient of x in the left hand side = 4 and the coefficient of x in the right hand side = 2
∵ 4x - 2x = 2x
Now we need two numerical terms their difference is 1 like 5 and 6 or 6 and 7 or 7 and 8 or 8 and 9
Let us take 5 and 6
∵ 4x + 5 = 2x + 6
- Subtract 2x from both sides
∴ 2x + 5 = 6
- Subtract 5 from both sides
∴ 2x = 1
- Divide both sides by 2
∴ x =
∴ The solution is
The equation is 4x + 5 = 2x + 6

Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
Step-by-step explanation:
3x - 5x - 4 - x^2 + 12x - 17x^2 - 16
= -2x - 20 - 18x^2 + 12x
= 10x - 20 - 18x^2
Hope it helpz~ uh..
Answer: 1
Step-by-step explanation:
To solve/simplify this all you have to do is group like terms (the x^2's with each other, the x's with each other, and the normal numbers, -8)
14x^2-8+5x-6x^2+2x
group the x^2 (add 14x^2 to -6x^2)
8x^2-8+5x+2x
group the x's together (add 5x and 2x together)
8x^2+7x-8
Your answer will be d) 8x^2+7x-8
