HELP

The linear equation 15(30x−5)=7−2(3+x)−4x has how many solutions?


no solution


exactly one solution


exactly two solutions


infinitely many solutions

Answer 1

exactly one solution

Explanation:

Solving the equation,

15(30x - 5) = 7 - 2(3+x) - 4x

450x - 75 = 7 - 6 - 2x - 4x

450x - 75 = 1 -6x

456x = 76

x = 76/ 456

x = 1/6

Since the equation has a single value = 1/6 that is true for the equation, it has one solution.
