[tex]\boxed{\sf Step\: By\:Step:- }[/tex]

[tex]\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)[/tex]

Remove the parentheses:

[tex]\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24[/tex]

Combine like terms:

[tex]\sf ^*7x-x=6x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24[/tex]

Multiply 3 and 5x = 15x:-

[tex]\to\sf 3x-\left(2x-1\right)=6x-15x+24[/tex]

Combine like terms:

[tex]\sf ^*6x-15x=-9x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=-9x+24[/tex]

Expand: 3x-(2x-1)= x+1

[tex]\to\sf x+1=-9x+24[/tex]

Subtract 1 from both sides:

[tex]\to\sf x+1-1=-9x+24-1[/tex]

[tex]\to\sf x=-9x+23[/tex]

Add 9x to both sides:

[tex]\to\sf x+9x=-9x+23+9x[/tex]

[tex]\to\sf 10x=23[/tex]

Divide both sides by 10:

[tex]\to\sf \cfrac{10x}{10}=\cfrac{23}{10}[/tex]

[tex]\to\sf x=\cfrac{23}{10}[/tex]
