Answer:

Question :-

value of x in equation 5x+7=3(x-2)+3

Required Answer :-

-5

Solution :-

5x+7=3(x-2)+3

5x + 7 = 3 \times x - 3 \times 2 + 3

5x + 7 = 3x - 6 + 3

5x - 3x =  - 6 + 3 - 7

2x =  - 10

x =  \frac{-10 }{2}

x =  \frac{ - 1 \cancel0}{ \cancel2}

x =  - 5

Verification :-

To verify we will substitute -5 in place of x

 5x+7=3(x-2)+3

5 \times  - 5 + 7 = 3( - 5 - 2) + 3

 - 25 + 7 =  - 15 - 6 + 3

 - 18 =  - 18

LSH = RHS

Hence verified
