a = 2x + 6xz
a = x(2 + 6z) <em>factored out "x" on right side</em>
a/(2 + 6z) = x <em>divided both sides by (2 + 6z)</em>
Answer: x = 
Answer:
10 classes
Step-by-step explanation:
Given equations in the question
Dance World: y = 15x
Toe Tappers: y = 25 + 12.5x
Where,
x = number of classes
Equate the total cost at both dance studios
15x = 25 + 12.5x
Collect like terms
15x - 12.5x = 25
2.5x = 25
Divide both sides by 2.5
2.5x / 2.5 = 25 / 2.5
x = 10 classes
x = number of classes = 10
