Step-by-step explanation:

Question :-

 \frac{6x - 15}{4}  -  \frac{35 - 25x}{6}  =  \frac{7x}{3}

To find :-

  • Value of "x"

Solution :-

  • Step 1

Multiply both sides of equation by 12 , the least Comman multiple of 4,6,3.

3(6x - 15) - 2(35 - 25x) = 4 \times 7x

  • Step 2

Use the distributive property to multiply 3 by 6x - 15.

18x - 45 - 2(35 - 25x) = 4 \times 7x

[ Expand using distributive property ]

  • Step 3

Use distributive property to multiply - 2 by 35 - 25x

18x - 45 - 70 + 50x = 4 \times 7x

[ Expand using distributive propert y ]

  • Step 4

Subtract 70 from - 45 to get - 115

18x - 115 + 50x = 4 \times 7x

[ Subtract one term from another ]

  • Step 5

Combine 18x and 50x to get 68x

68x - 115 = 4 \times 7x

[ Combine one term ]

  • Step 6

Multiply 4 and 7 to get 28

68x - 115 = 28x

[ Multiply two factor together ]

  • Step 7

Subtract 28x from both sides

68x - 115 - 28x = 0

  • Step 8

Combine 68x and - 28x to get 40x

40x - 115 = 0

  • Step 9

Add 115 to both side . Anything plus zero give itself.

40x = 115

  • Step 10

Divide both side by 40

x =  \frac{115}{40}

  • Step 11

x =  \frac{23}{8}

x =  \frac{23}{8}  = 2 \frac{7}{8}  = 2.875

Answer :- x = 2.875
