Answer 3

To solve the equation 3×(2x-1)+7=5(x-1)+x+9, follow these steps:

1. Distribute the constants and variables on the right side of the equation: 3×(2x-1) + 7 = 5x - 5 + x + 9

2. Simplify each side of the equation: 6x - 3 + 7 = 6x + 4

3. Combine like terms on each side: 6x + 4 = 6x + 4

At this point, you can see that both sides of the equation are equal, which means that the equation is an identity. This means that the solution is all real numbers. In other words, any value of x will satisfy the equation.
