3x + 17 + 5x = 7x + 10

- 7

Step-by-step explanation:

3x + 17 + 5x = 7x + 10

or, 3x + 5x - 7x = 10 - 17 ( take all the variables in one side and all the constants in another side)

or, 8x - 7x = -7

or, x = -7

you can check the answer by putting x = -7 into the equation. after putting the value of x if the Right hand side and left hand side of the equation become same, then your answer is correct.

if not, you need to check the steps again.
