How many solutions are there to the equation below?

elena55 [62]

Answer:

A) 0 (no solutions)

Step-by-step explanation:

Solve the equation:

3x - 10(x+2) = 13 - 7x

3x - 10x -20 = 13 - 7x

-7x - 20 = 13 - 7x

-20 = 13

Since both sides are clearly not equal to each other, no solution can satisfy both sides to be equal to each other. So A is correct.
