Answer:
Step-by-step explanation:
To determine whether 5x + 30 = 45 - 4x is equivalent to 9x = 15, we need to find the value of x that makes both equations true.First, let's solve the equation 5x + 30 = 45 - 4x for x. We can do this by adding 4x to both sides of the equation to get:5x + 4x + 30 = 45
9x + 30 = 45Subtracting 30 from both sides gives us:9x = 15This is the same as the equation 9x = 15, so we can conclude that the two equations are equivalent.
