What is the value of x, when -9(x-5)=x+22 1/2

Answers

Answer:

$\large\boxed{x=(9)/(4)=2(1)/(4)}$

Step-by-step explanation:

$-9(x-5)=x+22(1)/(2)\qquad\text{multiply both sides by 2}\n\n(2)(-9)(x-5)=2x+(2)\left(22(1)/(2)\right)\n\n-18(x-5)=2x+45\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\n\n(-18)(x)+(-18)(-5)=2x+45\n\n-18x+90=2x+45\qquad\text{subtract 90 from both sides}\n\n-18x+90-90=2x+45-90\n\n-18x=2x-45\qquad\text{subtract}\ 2x\ \text{from both sides}\n\n-18x-2x=2x-2x-45\n\n-20x=-45\qquad\text{divide both sides by (-20)}\n\n(-20x)/(-20)=(-45)/(-20)\n\nx=(45:5)/(20:5)\n\nx=(9)/(4)\to x=2(1)/(4)$

Answer:

x = 2.25

Step-by-step explanation:

-9(x - 5) = x + 22 1/2

Distribute the nine and then add 9x to both sides

-9x + 45 = x +22 1/2

+ 9x + 9x

Then try to get x alone

45 = 10x + 22 1/2

-22 1/2 -22 1/2

22.5 = 10x

$(22.5)/(10) = (10x)/(10)$

2.25 = x

Hi could you be so kind and solve this
3x+4=2x-7x-9
Thank you!

Answers

Alright for this you need these rules:
Group everything together
When isolating the variable do the opposite operation and do it on both sides.
You'll see what I mean
So for this it's 3x+4 = 2x-7x-9. So on the side with the -9 group the two variables together. Now you have -5x.
3x+4=-5x-9.
Now just subtract four from the side with 3x, as we are isolating the variable, and subtract it also from the other side, follow the rule. Now you have 3x=-5x-13. Next do what I did with the 4 and ADD 5x to each side, now you have 8x = 13. Divide each side to isolate even further and get x = 13/8.
Your final answer is:
x = 1 5/8

$3x+4=2x-7x-9\n \n 3x-2x+7x=-9-4\n \n 8x=-13\n \n \boxed{x=-(13)/(8)}$
