Asssuming blanks are plus
5(x+1)=4(x+8)
distribute
a(b+c)=ab+ac
5(x+1)=5x+5
4(x+8)=4x+32
5x+5=4x+32
minus 4x from both sides
x+5=32
minus 5 from both sides
x=27
Answer:
√(50)
Step-by-step explanation:
Hope that helps
Have A good day
can I have brain pls THXS
1)x+30=40
x=40-30
Answer :x=10
2)30-20+2x=10
10+2x=10
2x=0
Answer: x=0
3)3x-10+13=-2x+28
3x+3=-2x+28
3x+2x+3=28
3x+2x=28-3
5x=28-3
5x=25
x=5
4)13x-23-45=-7x+12
13x-68=-7x+12
13x+7x-68=12
13x+7x=12+68
20x=12+68
20x=80
x=4
5)2(x+4)=10x+24
2x+8=10x+24
2x-10x+8=24
2x-10x=24-8
-8x=24-8
-8x=16
x=-2
6)3(x-5)=1-(2x-4)
3x-15=1-(2x-4)
3x-15=1-2x+4
3x-15=5-2x
3x+2x-15=5
3x+2x=5+15
5x=5+15
5x=20
x=4
7)5x-10=15
5x=15+10
5x=25
x=5
8)x+4=x+6
4=6

Answer:
![\large\boxed{\dfrac{7n}{30}=\dfrac{7}{30}n}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Cdfrac%7B7n%7D%7B30%7D%3D%5Cdfrac%7B7%7D%7B30%7Dn%7D)
Step-by-step explanation:
![\dfrac{2n}{5}+\left(-\dfrac{n}{6}\right)=\dfrac{2n}{5}-\dfrac{n}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B2n%7D%7B5%7D%2B%5Cleft%28-%5Cdfrac%7Bn%7D%7B6%7D%5Cright%29%3D%5Cdfrac%7B2n%7D%7B5%7D-%5Cdfrac%7Bn%7D%7B6%7D)
To subtract both fractions we need a common denominator.
![LCD=(5)(6)=30](https://tex.z-dn.net/?f=LCD%3D%285%29%286%29%3D30)
![\dfrac{2n}{5}=\dfrac{2n\cdot6}{5\cdot6}=\dfrac{12n}{30}\\\\\dfrac{n}{6}=\dfrac{n\cdot5}{6\cdot5}=\dfrac{5n}{30}](https://tex.z-dn.net/?f=%5Cdfrac%7B2n%7D%7B5%7D%3D%5Cdfrac%7B2n%5Ccdot6%7D%7B5%5Ccdot6%7D%3D%5Cdfrac%7B12n%7D%7B30%7D%5C%5C%5C%5C%5Cdfrac%7Bn%7D%7B6%7D%3D%5Cdfrac%7Bn%5Ccdot5%7D%7B6%5Ccdot5%7D%3D%5Cdfrac%7B5n%7D%7B30%7D)
Therfore
![\dfrac{2n}{5}-\dfrac{n}{6}=\dfrac{12n}{30}-\dfrac{5n}{30}=\dfrac{12n-5n}{30}=\dfrac{7n}{30}=\dfrac{7}{30}n](https://tex.z-dn.net/?f=%5Cdfrac%7B2n%7D%7B5%7D-%5Cdfrac%7Bn%7D%7B6%7D%3D%5Cdfrac%7B12n%7D%7B30%7D-%5Cdfrac%7B5n%7D%7B30%7D%3D%5Cdfrac%7B12n-5n%7D%7B30%7D%3D%5Cdfrac%7B7n%7D%7B30%7D%3D%5Cdfrac%7B7%7D%7B30%7Dn)
