Answer :

The solution to the equation 4x + 10 + 3x = 40 - 3x is as follows: 1. Combine like terms on both sides of the equation: 4x + 10 + 3x = 40 - 3x 7x + 10 = 40 - 3x 2. Add 3x to both sides to get all the x terms on one side of the equation: 7x + 10 + 3x = 40 - 3x + 3x 10x + 10 = 40 3. Subtract 10 from both sides to isolate the x term: 10x + 10 - 10 = 40 - 10 10x = 30 4. Divide by 10 on both sides to solve for x: 10x/10 = 30/10 x = 3 Therefore, the solution to the equation is x = 3, which corresponds to option A.
