Question

Why does the equation 7x + 13x - 5 - 15 = -10 - 10 + 14x + 6x have an infinite number of solutions?

A. because if you add 20x to both sides of the equation and simplify you get -20 = -20

B. because if you add 20x to both sides of the equation and simplify you get -20 = 0

C. because if you subtract 20x from both sides of the equation and simplify you get -20 = -20

D. because if you subtract 20 X from both sides of the equation and simplify you get -20x = 0

Answer 1

Step-by-step explanation:

C

7x+13x-5-15=-10-10+14x+6x

Add 20x and both sides and simplify we get

-20=-20
