3.18x+2.6+0.9x+x=28
Find the value of x.
1st we add like terms>>
3.18x+0.9x+x=5.1x
>>5.1x=28-2.6
2nd we isolate x alone>>
>>5.1x=25.4
>>x=25.4/5.1
x=5
Add 3.18x + .9x + 1x = 5.08x
Subtract 2.6 to both sides
Divide both sides by 5.08 to get the solution for x
3.18x+2.6+0.9x+x=28
5.08x = 24.4
x = 24.4/5.08 = 5
Hali's equation of 5.1x = 25.4 -->(no idea where that came from ) does not yield the solution of x = 5 as he concluded.
To find the value of x in the equation 3.18x + 2.6 + 0.9x + x = 28, we need to combine like terms and then solve for x.
First, combine the terms with x: 3.18x + 0.9x + x = 4.08x.
Now, we can rewrite the equation as 4.08x + 2.6 = 28.
To isolate x, we need to get rid of the constant term 2.6. We can do this by subtracting 2.6 from both sides of the equation:
4.08x + 2.6 - 2.6 = 28 - 2.6.
Simplifying the equation, we have:
4.08x = 25.4.
Finally, to solve for x, divide both sides of the equation by 4.08:
4.08x / 4.08 = 25.4 / 4.08.
This simplifies to:
x ≈ 6.22.
Therefore, the value of x is approximately 6.22.
