How many solutions does 3x+18=5x+8 have?

1 answer

To find the number of solutions, we need to solve the equation 3x + 18 = 5x + 8.

Start by subtracting 3x from both sides of the equation: 18 = 2x + 8.

Next, subtract 8 from both sides: 10 = 2x.

Finally, divide both sides by 2: 5 = x.

Thus, the equation has one solution, which is x = 5.
